I’ve been cooking the same trio of curries for quite a while now, and thought it would be best to do something , if not completely different, then slightly different. Most curries made by myself are tomato based; goan curry, however, contains no tomato and is entirely yoghurt based. This does two things: firstly, it makes the curry a lot smoother; and, secondly, it reduces the cost somewhat over a curry which uses both yoghurt and tomato.
