Clean the banana stem and roughly chop the required quantity. Take it in a small pressure cooker/pan along with peppercorns, cumin, ginger, and green chilies along with 2 cups water.

Pressure cook for 4 whistles/ 15 minutes and let the pressure release naturally.

Use a colander and drain out the water used to cook the banana stem and reserve the liquid.

Grind the remaining solids to a fine paste.

Again filter this and transfer it to a pan along with the reserved water. Add more water if needed. Bring to a boil.

Add salt and simmer for a minute

Serve hot garnished with coriander leaves
