If you’re not happy with the heat level of your butter chicken gravy, there are a few simple fixes you can make. For example, you can add a small amount of yogurt (or coconut milk) to soften the gravy. You can also add a little honey or sugar to balance the taste. Remember that it’s better to start adding more spices slowly than to add too much later. If you’re looking for a lighter gravy, you can always start with a little chili powder or other spices.
