Usuna Arna
A traditional Bengali dish where raw green mango is simmered in a sharp, pungent mustard paste. The tangy tartness of unripe mango meets the fiery kick of mustard and green chilies, creating a thin, soupy curry that awakens the palate.

What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Always soak the black mustard seeds before grinding to achieve a smooth, non-bitter paste.
- 2Use a mortar and pestle or a spice grinder for the mustard paste; blenders can turn it bitter.
- 3Bring the mustard oil to its smoking point and let it cool slightly before adding chilies to avoid scorching.
- 4Taste a piece of raw mango before cooking; if too fibrous or sour, adjust sugar accordingly.
- 5Simmer uncovered if you prefer a thicker gravy; cover for a soupier consistency.
- 6For the best texture, slice mango strips evenly so they cook at the same rate.
