Kol Posola Bhaji
A delicate Bengali stir-fry made from the tender inner core of a banana stem, known as 'thor'. The crisp, mildly sweet stem is finely chopped, quickly blanched, and then sautéed with mustard seeds, green chilies, and freshly grated coconut. This light, vegan dish is wonderfully crunchy and pairs beautifully with steamed rice and dal.

What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Choose a fresh, firm banana stem with no browning or soft spots for best texture.
- 2Oil your hands before peeling the stem to prevent sticky sap from staining your skin.
- 3Blanch only 2-3 minutes; the stem should stay crunchy, not mushy.
- 4Use a kadai or wide pan for even heat distribution and quick moisture evaporation.
- 5Let the mustard seeds splutter fully before adding chilies to deepen their nutty flavor.
- 6Add the pinch of sugar even if you prefer savory dishes—it rounds out the stem's natural bitterness.
- 7Serve immediately after cooking; the bhaji loses its crunch if left to sit too long.
