I recommend freezing the curry paste in big silicone ice cube trays. That way you can store them and pop them out as needed. Honestly, it makes it really convenient! As for applications, you can use the curry paste on its own to crust fish. Or, add it to coconut milk to make actual curry with veggies or a protein. You can add some to vinegar with some shallots to make mignonette. Your imagination is the limit!
