Thai green curry is typically made with green chilis which is what gives it the distinct green color. Other ingredients include shallots, galangal, garlic, lemongrass, kaffir lime leaves, and Thai sweet basil. A little goes a long way when you use Thai green curry. It's big on spice! I use a store bought green curry paste, but if you're feeling up to it this is an excellent recipe for a homemade Thai Green Curry by Curious Cuisiniére.
