Look for cans of coconut milk in the international cuisine section of your grocery store. To avoid confusion while you're shopping, be aware that there are a couple of other products with similar names. You do not want the carton of coconut milk that is stocked in the dairy case with the almond milk and is used as a non-dairy milk substitute. And, you do not want canned coconut cream, which is basically an entire can of the rich top layer you find in coconut milk.
