RE: Picadillo taco
Well, as I pointed out in a post earlier this eve, the addition of finely chopped potato should allow you to get rid of all the grease in the beef, yet still retain a nice savory moistness. I hate dry and crumbly tacos. Can't help you with the spices, I would assume a little chili powder, cumin and garlic wouldn't hurt, maybe drain the grease, add a little water to the pan, stir in the spices, and simmer till it looks right. Shells? Find the thinnest ones you can.
