Coconut milk is made from shredded coconut that is simmered in water and then strained to make a creamy liquid. It should not be confused with coconut cream, which has less water, or with sweetened cream of coconut. Reduced-fat coconut milk contains thickeners and other additives; it's best to use small amounts of regular coconut milk instead.
Very good. I made a few changes though. I had cooked my red snapper whole...used half of the meat for tacos and saved the other half for the soup. I cooked the bones and head in water and made fish stock and subbed it in for the regular water. I also left out the lime and added a little ginger simple syrup that I made a few days earlier. Wonderful soup!
