Slit the green chillies lengthwise; do not split
Sieve gram flour, add salt, chilli powder, cumin/coriander powder, garlic paste, lemon juice, sugar, turmeric, 1/4 cup water and bind with oil
The mixture should be slightly runny so that it can be spooned into the chillies
Stuff chilies with this mixture
Heat 4 tbsp oil in a frying pan. When hot, put in fenugreek seeds. After a few seconds add the mustard and cumin seeds. When these pop, put in the stuffed chillies and reduce to very low heat heat
Turn them occasionally ensuring that they do not turn brown
Chilies are ready to serve when the skin has turned soft
Place chillies on the serving plate, drain away excess oil from the frying pan and sprinkle all the cooked seeds on the chilies together with a little salt
