I am allergic to dairy, but love creme caramel. I tried making a classic creme caramel with coconut milk to see how it compares to the real thing. While the texture is not 100% the same as making it with regular milk, it is still very delicious and much appreciated for those of us who are allergic to dairy or lactose intolerant!
While I haven't tried it, you could try making this with half coconut milk and half soya milk. But my husband said he couldn't really detect much coconut flavour, and I must admit - it doesn't really taste that coconutty.
