There are as many variations on this as there are days in the year. I suggest you troll about on the Interweb to see what some of the other recipes look like. This stuff is pretty much good on anything.

1 cup shelled walnuts

4 whole dried chiles (or fresh)

1/2 c yogurt

1/4 t garam masala

1/2 t salt

1t powdered sugar

In food processor, grind walnuts and chiles to a paste. Add the rest of the ingredients and process for about a minute. One of those little food processors works best if you are making a single batch.
