Yes, you can substitute curry paste for curry powder. However, keep in mind that the flavor profile will be slightly different. Red curry paste is generally more spiced and fragrant and is commonly used in Thai curries. It contains various spices, oils, and fresh ingredients like ginger or garlic. Curry powder, on the other hand, is mildly spiced and is a staple in Indian cooking, containing only dried spices. If you want to make the swap, we recommend using 1 tablespoon of curry paste.
