Soppin khar is a traditional dish from Assam that is made with bamboo shoots and khar, which is an alkaline ingredient made from burnt banana tree trunks. The dish is known for its unique and distinctive taste. Here is a simple recipe for soppin khar:
In a bowl, mix the khar with 1/2 cup water and stir well until dissolved.
Heat the mustard oil in a pan and add the chopped onion and green chilies. Saute until the onion turns translucent.
Add the finely chopped bamboo shoots to the pan and stir-fry for a few minutes.
Add the khar solution, turmeric powder, salt, and enough water to cover the bamboo shoots. Bring to a boil, then reduce the heat and simmer for about 15-20 minutes, or until the bamboo shoots are cooked through and the curry has thickened.
Serve hot with steamed rice.
Notes
Khar should be used sparingly, as it is a strong alkaline ingredient and can cause indigestion if consumed in large amounts. Bamboo shoots can also cause digestive issues in some people, so it's best to start with small amounts and see how your body reacts.
