Cucumber tambuli Recipe is a cold yogurt side dish from Karnataka that takes less than 15 minutes to make and needs almost no cooking. It is cooling, lightly spiced, and goes beautifully with hot steamed rice.
If you have ever had a day when you are hungry but cannot bring yourself to stand at the stove and cook, this is the recipe you want. (step-by-step-recipe-video)
What is Cucumber Tambuli?
Cucumber tambuli is a no-cook yogurt dish from the Udupi and coastal Karnataka tradition.
You grind fresh cucumber with coconut, green chilli, garlic, cumin, coriander and pepper into a smooth paste, mix it into curd with water, and finish it with a quick tempering of mustard seeds, dry red chilli and curry leaves.
The result is something between a raita and a thin curry, cool, fragrant, and deeply satisfying with rice.
What makes it different from a regular cucumber raita is the coconut and the grinding. A raita is just grated cucumber stirred into curd. Tambuli has that coconut-spice paste running through every sip, giving it body and warmth even though it is served cold.
It is also sometimes called cucumber dahi tadka in North India, though the two are cousins, not the same dish.
The word tambuli comes from “thampu,” which in Kannada means cool or cold.
These dishes were traditionally prepared in the summer months to bring relief from the heat. They are still made the same way, in the same homes, for the same reason.
Regional Variations of Tambuli
Tambuli is made all along the Karnataka coast and the Malnad region, and every household has its own version.
In Udupi, the tambuli is made with minimal spices, just coconut, green chilli and cumin, with a light mustard tempering. The focus is on the cooling quality of the main ingredient, whether it is cucumber, coriander, or horsegram. Udupi tambuli is thinner and more drink-like.
In the Mangalore belt, cooks sometimes use Mangalore cucumber, which is the pale yellow dosakaya variety. The seeds of this cucumber are ground separately into the paste, adding a distinct earthiness that regular cucumber does not have.
In Coorg and the Malnad areas, tambuli is sometimes made with wild herbs like doddapatre (Indian borage) or ginger. These versions lean more medicinal and are often given to people recovering from illness or to new mothers.
In my kitchen in South India, I make it with the regular green cucumber we find everywhere. Two cucumbers, a handful of coconut, some coriander, and a hot tadka poured on top just before serving.
It is the version I keep coming back to.
Preparation Tips for Best Results
Use fresh coconut if you can. The dish tastes noticeably better with fresh grated coconut than with desiccated or frozen. If fresh coconut is not available, frozen grated coconut thawed to room temperature is the next best option.
Do not skip the garlic. Some recipes leave it out. The garlic gives the paste a slight sharpness that balances the cool curd and coconut. Without it, the tambuli can taste flat.
Adjust the green chillies to your family’s spice tolerance. Four chillies makes a moderately spiced tambuli. If you are making it for children or people who prefer mild food, use two chillies and remove the seeds.
Grind the paste smooth. The finer the grind, the better the final texture. Stop, scrape the sides of the jar, and grind again if needed. A coarse paste makes the tambuli feel gritty.
Use cold curd. Room temperature curd works, but cold curd straight from the fridge makes the final dish more refreshing. On a hot afternoon, this small thing makes a real difference.
Add the water gradually. Start with 2 cups and check the consistency. Some families prefer it thicker, almost like a raita. Others like it thin enough to drink alongside rice. Adjust to what feels right in your home.
Pour the tempering on just before serving. Once the hot tadka hits the cold tambuli, it blooms into the dish within seconds. If you are making this ahead of time, store the tambuli and prepare the tempering fresh when you sit down to eat.
Troubleshooting: if your tambuli tastes too sharp or sour, your curd may be very fermented. Balance it with a little extra water and a pinch of sugar. If it tastes bland, add a small pinch of salt and grind in one more green chilli.
Why This Recipe Works
This recipe is simple because it does not fight itself. Each ingredient has a clear job, and none of them get in each other’s way.
The cucumber does the cooling work. It has a high water content and a mild sweetness that forms the base of the dish.
The fresh coconut adds richness and body, so the tambuli does not feel thin even though it is a cold dish. The coriander and garlic bring freshness and a little edge.
The curd ties everything together with its gentle sourness.
The tempering is what makes it feel like food and not just a dip. Hot oil, crackling mustard seeds, dry red chilli and curry leaves.
That single minute of cooking does more for the flavour than any number of extra ingredients would. The heat releases the oils from the curry leaves and chilli into the dish, so you get warmth alongside cold in every spoonful.
It is also a very forgiving recipe. You can add more water if you want it thinner. You can add less chilli if you want it milder. You can use mint instead of coriander if that is what you have.
The core stays the same. The variations are all yours.
The First Time I Had Tambuli Was at a Friend’s Home in Karnataka
I did not grow up eating tambuli. Back in Bihar, curd meant raita or lassi. A cold yogurt dish with ground coconut and a mustard tadka was not something I had ever seen on a lunch table.
The first time I had it was at a friend’s house here in Karnataka. It was a hot afternoon, the kind where you do not want to eat much but your body still needs something.
Her mother had made a simple lunch, plain rice, a dry sabzi, and this bowl of something pale green and cool sitting in the middle of the table.
I did not know what it was. I watched my friend pour it over her rice the way you would pour rasam, and I did the same.
The first spoonful was a surprise. Cool and coconutty, with a little heat from the chilli and that burst of curry leaf from the tadka.
Nothing heavy, nothing complicated. Just something that made sense on a hot day.
I asked her mother what it was called.
Tambuli, she said. Cucumber tambuli.
She had made it in under fifteen minutes while we were sitting in the other room talking.
I went home thinking about it. The next week I called my friend and asked for the recipe. That was a few years ago now.
I have made it so many times since that it has quietly become a part of how I cook in summer, the same way it has always been a part of how families in Karnataka eat.
Some recipes travel with you. This one found me here, far from home, at a friend’s lunch table on a hot afternoon.
And I am glad it did.
What to Serve with Cucumber Tambuli
Cucumber tambuli is a side dish for rice. Hot steamed rice with tambuli poured over it is the most traditional and satisfying way to eat it. You do not need much else.
If you want to make it a complete meal, a dry vegetable stir-fry on the side works well.
Aloo palya or a simple beans fry pairs nicely because the crunch and spice of the sabzi balances the cool creaminess of the tambuli.
A papad and pickle alongside is a simple addition that many Karnataka families serve without thinking twice.
You can also serve tambuli as part of a full rice meal with sambar or rasam on the other side. In that case, treat the tambuli as the cool counterpart to the hot dishes.
Storage
Cucumber tambuli is best eaten fresh, the same day you make it.
Because it is made with curd and has no cooking to preserve it, it does not store as well as cooked dishes.
If you have leftovers, refrigerate in a covered bowl and eat within one day.
The curd may separate slightly after a few hours. Just stir it back together before serving.
Do not reheat. This is a cold dish and should stay cold.
The tempering, once poured in, does not stay crisp. So if you are making this for a meal later in the day, keep the tambuli and the tempering separate and combine just before eating.
Do not freeze. The curd will split on thawing and the texture will not come back.
Pro Tips for Perfect Cucumber Tambuli Recipe:
Peel the cucumber if the skin is thick or bitter. Most regular green cucumbers in India have a thin, mild skin that grinds fine.
Taste a small piece before you grind. If it is bitter, peel it.
Toast the cumin before grinding if you want a slightly deeper flavour. Dry roast the jeera in a pan for 30 seconds until fragrant, then let it cool before adding to the jar.
Use the full coriander, stalks and all. The stalks have more flavour than the leaves and grind down completely.
Do not discard them.
Chill the serving bowl. If you have 10 extra minutes, keep your serving bowl in the fridge while you prepare the tambuli.
It keeps the dish cold for longer at the table.
Make the tempering last and pour it immediately. The heat of the tadka should hit the cold tambuli while it is still sizzling.
This is what creates that contrast of hot and cold that makes the dish so satisfying.
If you are grinding in a small mixie jar, cut the cucumber into smaller pieces so it does not cause the jar to overflow or grind unevenly.
For a slightly thicker tambuli, reduce the water to 1.5 cups. For a thinner, more drinkable consistency, use 3 to 3.5 cups.
The dry red chillies in the tempering are for flavour and colour. They do not add much heat after the tadka. If you want more heat in the tempering, add half a slit fresh green chilli to the oil.
Black pepper in the paste gives background warmth without the sharpness of chilli. Do not leave it out.
If you do not have fresh coconut, use 4 tablespoons of coconut milk instead. The texture will be slightly smoother and less thick, but the flavour holds.
Serve in small steel bowls or katoris in the traditional Karnataka style. The metal keeps the dish cold longer than ceramic.

Basic Ingredients Used to Make Cucumber Tambli:
Cucumber: The base of this dish. Cucumber is mostly water, which keeps the tambuli cool and light. Use regular green cucumbers with thin, mild skin. Make sure they are fresh and firm.
Soft or overripe cucumbers will make the tambuli watery and slightly bitter.
Fresh Coconut: Coconut gives the paste its body and a natural sweetness that balances the sour curd. Fresh grated coconut grinds into a smooth, creamy paste better than any other form.
If you are using frozen coconut, thaw it completely and drain any excess water before adding it to the mixer.
Curd: The main liquid of the dish. Use full-fat homemade curd for the best flavour. It should be fresh and not overly sour.
Very fermented curd will make the tambuli sharp and sour rather than cool and balanced. If your curd is thick, use a little extra water to get the consistency right.
Green Chilli: Adds the heat element that stops the dish from tasting flat. Four chillies is moderate for most palates. Adjust based on how spicy your family likes their food.
Garlic: Brings depth and a slight sharpness to the paste. Just six cloves, but you will notice if they are missing. Garlic gives the tambuli its edge and makes it feel more complete as a dish.
Cumin (Jeera): Adds a warm, earthy note to the paste. Cumin works well with curd-based dishes and has a long history in Ayurvedic cooking as a digestive aid. It rounds out the flavours of coconut and cucumber nicely.
Black Pepper: Subtle background heat and warmth. Just half a teaspoon in the paste, but it adds a layer you can feel rather than taste directly.
It also helps digestion, which is why tambuli was traditionally eaten as a starter course in a traditional Karnataka meal.
Coriander Leaves: Freshness and colour. Use the full handful including the stalks. The stalks carry most of the flavour and grind smoothly. Fresh coriander lifts the whole paste and gives the tambuli a clean, bright character.
Dry Red Chilli (for tempering): Adds colour and a toasted, smoky note to the tadka. These chillies do not make the dish very hot, they are in the tempering briefly and then rest on top. Their job is more flavour than fire.
Mustard Seeds: The crackling sound when mustard seeds hit hot oil is one of the most satisfying things in an Indian kitchen.
In tambuli, they add a light nuttiness and a pop of flavour that runs through the dish.
Curry Leaves: Irreplaceable. Fresh curry leaves in hot oil release a fragrance that you cannot get from any substitute. If you do not have fresh curry leaves, dried ones work at a fraction of the impact, but they are better than nothing.

Making the Paste
Add chopped cucumber, black pepper, jeera, green chilli, garlic, fresh coconut, coriander leaves and salt into a mixer jar. Add a little water and grind everything into a smooth paste.
Stop and scrape the sides once in between, then grind again until there are no rough bits left.
Mixing the Tambuli
Transfer the paste into a large bowl. Add the curd and the remaining water. Mix everything together well until you get a smooth, slightly thin consistency.
Taste and adjust the salt if needed. You can also adjust the water at this stage depending on how thick or thin you like your tambuli.
Making the Tempering
Heat oil in a small pan. Add the mustard seeds and let them crackle fully. Add the dry red chillies and curry leaves.
Let them splutter for a few seconds, the curry leaves will hiss and turn slightly dark at the edges. Take the pan off the heat.
Finishing the Dish
Pour the hot tempering directly over the tambuli and mix it in gently. Serve immediately with hot steamed rice.

Notes
Frequently Asked Questions About This Southekayi Tambuli:
What is cucumber tambuli?
Cucumber tambuli is a cold yogurt dish from Karnataka where fresh cucumber is ground with coconut, garlic, chilli and spices into a paste, mixed with curd and water, and finished with a hot mustard-curry leaf tempering. It is served with steamed rice and is especially popular in summer.
What is the difference between cucumber tambuli and cucumber raita?
Cucumber raita is just grated or chopped cucumber mixed into curd with a pinch of cumin and salt. Cucumber tambuli involves grinding the cucumber into a spiced coconut paste before mixing it with curd, which gives it much more depth of flavour and a thicker, more satisfying texture. The hot tempering poured on top also sets it apart.
Can I make cucumber tambuli without coconut?
You can, but the dish will taste lighter and thinner without coconut. If you do not have fresh coconut, use 4 tablespoons of coconut milk instead. The texture will change slightly but the flavour will be close.
How long can I store cucumber tambuli?
Cucumber tambuli is best eaten fresh. Refrigerate leftovers in a covered bowl and eat within one day. Stir well before serving as the curd may separate after a few hours in the fridge. Do not freeze.
Can I use buttermilk instead of curd?
Yes. Thin, spiced buttermilk (chaas) works well in this recipe. If using buttermilk, reduce the water you add separately or skip it entirely and adjust to your preferred consistency.
Why does my tambuli taste flat?
The most common reason is, not enough salt or too few chillies. Taste after mixing and add a pinch more salt. Also check that your curd is fresh and not overly watered down. A squeeze of lemon juice can also sharpen the flavour if needed.
What can I serve with cucumber tambuli besides rice?
Tambuli pairs best with plain steamed rice, but it also works alongside idli or dosa as a cooling side instead of coconut chutney. It goes well with a dry vegetable stir-fry on the side if you want a full meal.
Is cucumber tambuli good for digestion?
Cucumber has a high water content and curd has natural probiotics. Both are gentle on the stomach. Cumin and black pepper in the paste are traditional digestive spices used widely in Ayurvedic cooking. Tambuli was eaten as a starter in traditional Karnataka meals precisely because it was considered easy on the body.
Can I make this without garlic?
Yes, you can leave out the garlic for a Jain version or for personal preference. The dish will be milder and slightly less complex in flavour, but it will still taste good. Add an extra pinch of cumin to compensate.
What is the difference between tambuli and dahi tadka?
Dahi tadka is a general North Indian term for curd with a tempering poured over it. Cucumber tambuli is a specific South Indian dish with a ground paste base that makes it quite different from a simple dahi tadka. Both are cooling yogurt dishes, but tambuli has more complexity in the base.

If you enjoy making recipes like cucumber tambuli, chutneys, or coconut-based gravies at home, investing in a good quality mixer grinder can make the process much easier and quicker.
