Found this in a curry and chili cookbook. We actually didn't have any yoghurt the first time we made it. It was still great, just a little spicy. Edited the ingredients to change the amount of spinach - hopefully this amount will be more suitable :-)
I got this out of a "Taste of Home" Christmas issue a few years back. The lady who submitted this was Jewish, and this was her entree for her Hanukkah meal. I'm not Jewish, but I love lamb, and this recipe is a winner! The sweetness of the citrus fruits and the the heat from the spices really stand out!
