I have been hearing about burfi from my boyfriend's sisters for five years - "Burfi, mmmmm *drooling noises*" Last week Yamuna finally made some and it was so good it made my eyes roll back in my head. Needless to say it's not a diet food and a little bit goes a long way - make sure you've got a handful of people hanging around to help you eat this! Although it's not in the recipe and this tastes good as it is, I'd bet that a pinch of cardamom, saffron threads or rose water would taste wonderful in this recipe. Dried fruits like raisins or chopped dates could take the place of nuts as well. Will have to do some experimenting next time. UPDATE: In response to Sprue, I should have made it clear that you have to melt the butter and heat the milk very slowly. Otherwise the milk does burn before the sugar can dissolve properly. Once the milk is boiling you should lower heat to a very light simmer. Hope this helps!
