Take 1 tablespoon of ajwain seeds. Clean the seeds by discarding muds if any. Organic ajwain seeds won't have impurities in general. Heat a pan and dry roast ajwain seeds in low flame until crisp and nice aroma comes. It may take 3-5 minutes. Switch off the flame once done.

Transfer the roasted ajwain seeds into clean cotton cloth/muslin cloth. Bring the edges to center.

Put a knot tight to make a pouch/potli. Ajwain potli is ready!
