There is a wonderful Cuban bakery in Glendale, California called Porto's where I first tasted these. They are so delicious, and I was lucky enough to find a recipe for them in a Saveur magazine article about Cuba. You can't eat just one! NOTE: You only need 1 cup of the picadillo for the croquettes, so you will have a lot left over. The 6 servings apply only to the potato croquettes. You can serve the leftover picadillo over rice or make more of the potato mixture to make more croquettes.
