I love making curries. I do not have a specific recipe for korma, but if you googled it you would find one.
However, I would suggest you make a curry with mild and yellow spices, add cream (or yoghurt) and toasted almonds and you would have a close approximation.
I used to have a recipe site bookmarked with thousands of Indian and other recipes, but it seems to be gone. I THINK it was called something like Mamta's recipe site.
