Can you use coconut milk in place of half and half?

Yes, you can use coconut milk as a substitute for half and half, but the texture and flavor will differ. Coconut milk is creamier and has a distinct coconut flavor, which may alter the taste of your dish. For a closer match, you can mix equal parts coconut milk and water or use coconut cream diluted with a bit of water. Always consider the specific recipe and desired flavor profile when making the substitution.
