I tried this coconut-flavored treat when I needed something to take to a pot luck for my Filipino-American Experience class. It comes from Phillipine Recipes Made Easy (which seems to have a lot of authentic Filipino dishes). It seems to be just like the Hawaiian Haupia to me, except some Haupias have fruit mixed in. To dilute coconut milk, use 1/2-3/4 cup water to every 1 cup of milk. Make sure you use coconut MILK and NOT coconut CREAM or JUICE. Also, be sure to vigorously shake the can of milk before opening it or you will end up with separated layers that won't blend as well when heated.
