This is a very popular desert in the Philippines. Buko is young coconut flesh and is used in many foods here. When we first moved to the Philippines we were a little turned off by the idea of having corn and cheese in our fruit salad, but it's grown on me and now even my kids love it. Still, even though it's tradditionally made this way I've also been served buko salads once or twice that didn't add the corn and cheese, so I put it as optional. This recipe was given to me by my good Filipino friend and helper, Marina. Cooking time doesn't include freezing time. This can be eaten right out of the freezer when it's more frozen, after it's sat out and mostly melted, or it's even eaten completely melted sometimes.
