Add the flax seeds and roast them, stirring every few seconds to prevent burning.
The seeds will start popping like mustard seeds.
Keep a lid handy and cover in between stirring to avoid them jumping out.
Roast for about 3–4 minutes, until you get a warm, nutty aroma.
Turn off the flame and let the seeds cool down completely.
Once cooled, transfer them to a dry spice grinder and grind into a fine powder.
Store in an airtight container.
For longer freshness, refrigerate and use within 1 month.
If storing outside, finish within 3–4 days.
Notes
Always roast on low flame to avoid bitterness. Let seeds cool fully before grinding. Use only dry jars, moisture can spoil the powder.For the best taste, make in small batches and consume fresh.Tisi powder can be added to paratha dough, chutneys, sabudana khichdi, sattu, or even sprinkled on dal-chawal.
