The ingredients are the same in a can of coconut milk and a can of coconut cream. Typically the ingredients are: coconut, water, and sometimes guar gum as a stabilizer. However, the main difference is the fat content. The can of coconut cream has a higher amount of fat, because it contains more coconut and less water. Therefore, canned coconut cream has a more creamy and luxurious texture. Essentially, coconut milk is slightly more watered down version. But it works as a substitute in this recipe.
