Huatia
After the potato harvest in May and June, families in Puno, Cusco and across the highlands build a huatia in the field: a little dome of dry earth clods heated with dried brush until the clods glow, then knocked down over freshly dug potatoes and oca so they bake slowly underground. Opened an hour later, the potatoes are smoky, floury and so soft their skins split, and the oca turns sweet and tangy. Everyone eats them with their hands, with salt, chilli sauce and fresh cheese. This recipe gives an oven method for home cooks: a lidded pot bedded with coarse salt and herbs, which traps heat and steam much like the earth. If you do try a real huatia outdoors, use a clear patch of ground away from anything that can catch fire and keep water nearby. Don't uncover the pot early to check: the steam escapes and the potatoes turn leathery. Fresh oca is sold in some markets as New Zealand yam; small sweet potatoes will do. Chef's tip: choose potatoes of a similar size so they all finish together, and serve with uchucuta.
