We serve this as a dip or side with Onion Bhajias.
2 c plain yogurt
5 T besan (chickpea) flour
1/2 t chili powder
1/2 t turmeric
salt to taste
2 fresh green chili peppers, chopped fine
4 T olive oil
1/4 dried red chili flakes
1 t cumin seeds
3 cloves of garlic, minced or pressed
1 piece fresh ginger 1-2 inches long, grated
1 or 2 T chopped fresh cilantro
Mix yogurt, flour, chili powder, turmeric and salt in a saucepan. Add the chili peppers and cook gently for 10 minutes.
Heat oil in a frying pan and fry the remaining spices, garlic and ginger, cooking until the red pepper flakes darken. Add cilantro at the end, then pour the spices over the yogurt mixture. Cover the pan and leave to rest for 5 minutes off the heat, or until ready to serve. Then mix well and gently reheat before serving (about 5 minutes).
