Curry leaves are great!! I use them in most vegetable dishes as well as in the tarka for the dals I make. Asda carries them..I have not seem them anyplace else - except for indian stores. But they have rather large bags at the indian stores so I dont get them from there. If I buy a larger amount, I wash them, and put them in the freezer in ziploc bags - they work as good as new!!! Otherwise, they seem to go black and spoilt rather quickly. I am not sure if anyone here in England even makes dals and the such. if so, I could post a lentil recipe for anyone that cooks lentils. They almost always go hand in hand with black small mustard seeds - the combination is used in south indian cooking mostly. I plan on posting some recipes later this week.
