These are just like the tamales my Abuelita used to make for special occasions. This recipe makes a lot, but if you're going to go to all the trouble of making tamales from scratch, you might as well have a party! You will need butchers' twine and a large pot with a steamer basket to make these. May be frozen up to 6 months in heavy-duty resealable plastic bags. To reheat, thaw in refrigerator and then steam or microwave until heated through.
