Start with 1 tablespoon of curry paste and add more if you prefer it on the spicy side, or add a little less if you’re spice shy. Curry pastes are all a bit different. I use 2 tablespoons and it’s just the way I like it. Don’t worry if you only add a teaspoon, then when all the other ingredients are added you think you want it a bit spicier, just add some more and cook until it’s combined and heated, it’ll be fine.
Store sauce in refrigerator. If it’s a little too thick for you after its been refrigerated, just add a little water to thin it out.
