One typical and original plate of Puerto Rico is called "mofongo". Mofongo is generally made from fried green plantains, although fried yuca or breadfruit are possible, which is mashed together with broth, garlic, olive oil, and pork cracklings or bits of bacon. It is often filled with vegetables, chicken, crab, shrimp, or beef and is often served with fried meat and chicken broth soup. Mofongo relleno is mofongo stuffed with stewed beef, chicken or seafood, with stewed sauce poured over. Here is a picture of it:
Recipe1. Peel plaintains. Cut into one inch slices. Soak for 15 minutes in salt and water. Drain well.
2. Heat fat or oil(350 degrees if you are using a deep fryer). Add plaintain slices and fry for 15 minutes but do not brown. Drain on paper towel.
3. In a mortar(for pounding), crush garlic cloves and sprinkle with salt, add olive oil to the mixture and keep pounding.
4. Crush a portion of the fried plaintains slices and the pork. Add some of the garlic and olive oil mixture and keep pounding.
5. Spoon the mixture and shape into two inch balls. Repeat steps 3 and 4 until you use all the ingredients.
6.Place in oven pan and keep warm until you are ready to serve.
