Goes well with any Indian, but i like it with a bit of Beef Panang! Adjust quantities of the obvious to suit the number of diners, although they will be popular. This should be enough for 4.

10 curry leaves
1/4 teaspoon of turmeric
1/2 teaspoon of ground ginger
2 green chillies, finely chopped
2 onions. finely chopped
