"This recipe is very flexible, and is delicious no matter what spices you put in. If you don't have garam masala, feel free to throw in a few warm, aromatic spices - coriander would be great, as well as cumin or cardamom. Dried chilis would be an excellent addition, if you have them. The turmeric is always a must, for color as well as flavor. If it feels like you end up with a lot of curry, don't worry! This makes great leftovers."
