For preparing Kerala Style Pavakka Theeyal, first slice the onions and green chillies thinly.
Heat up a pan or kadai.
Fry coriander seeds, dry red chillies and grated coconut, till it turns brown.
:- If you are using powders, then fry only the coconut first and just before switching off the flame, add coriander powder and add chilly powder after switching off the flame.
Allow this to cool.
Grind the fried items in a mixer grinder along with enough water into a smooth paste.
Heat coconut oil in a pan or a kadai.
Splutter mustard seeds and saute dry red chillies and curry leaves.
Add sliced onions and saute well.
When sauteed, add bitter gourd pieces and sliced green chillies and saute well again.
When the whole thing gets sauteed well, add tamarind extract, salt and turmeric powder.
Mix well and allow it to boil.
Add the coconut paste along with enough water and mix well.
When Kerala Style Pavakka Theeyal reaches the desired consistency (neither too thin nor too thick), remove from flame.
