After roasting, let the cumin seeds sit for at least 5–10 minutes. Warm seeds create steam while grinding, which can cause clumping and dull the aroma.
Add the roasted seeds to a completely dry grinder bowl. Moisture is the enemy of good spice powder—it reduces shelf life and affects texture.
Use short pulses to break down the seeds gradually. This prevents overheating, which can make the powder taste slightly burnt.
Continue pulsing until the cumin becomes a fine, even powder. If you prefer a slightly coarse texture (great for sprinkling over salads or vegan raitas), stop a bit earlier.
If you want professional-level smoothness, pass the powder through a fine mesh sieve. Return any coarse bits to the grinder and pulse again.
Freshly ground spices warm up slightly from friction. Allow the powder to cool for a few minutes so condensation doesn’t form in the jar.
Keep in a glass jar with a tight lid, away from sunlight and heat. For best flavor, use within 1–2 months.
