These may well be the best-ever party snack (in fact, they might not even make it out of the kitchen). You can buy your tortillas, but they won't be as good as these rich, flaky ones. We've deep-fried them, but you can heat them in the oven if you prefer.
Note This recipe makes about 20 tortillas. For the best-tasting tortillas, make your own lard. Place diced pork back-fat in a saucepan, add enough water to just cover the base of the pan (adding more makes the pork flavour cook out), cook over low heat until fat is rendered, then strain.
