Note: have found out that these are called "Ice Cream Beans."
The trees are very large, the pods are very large and although I have no idea yet what they are called, I do know that they are very popular among ticos. The pods are quite long as you can see in the photo. Once you slash the side with your machete you can break the pod open over your knee. Inside are dark brown seeds covered with a white "fuzzy skin." You put the whole seed in your mouth and eat the sweet outer fuzz (spit out the remaining seed. They really are quite tasty!!!
