What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1For the smoothest paste, a traditional stone grinder (shil nora) is unparalleled. A small, powerful mixer-grinder or a coffee grinder is the next best option.
- 2The quality of mustard oil is crucial. Use a pungent, cold-pressed oil for the most authentic Bengali flavor.
- 3Do not add too much water while grinding. The goal is a thick paste. Too much water will dilute the flavor and ruin the texture.
- 4To avoid bitterness, ensure your poppy seeds are fresh and wash them thoroughly before soaking.
- 5Posto Bata tastes best when freshly made. It can be stored in an airtight container in the refrigerator for up to 2 days.
- 6Serve it as a side with steamed rice, dal, and a vegetable fry (bhaja) for a complete, traditional Bengali meal.
