Nopales En Bolso with Vegetables Escabeche

By cooking the nopales—the flat paddles of the prickly pear cactus—at a controlled temperature in a sturdy self-sealing plastic bag (en bolso), we are able to infuse flavors slowly into the nopales and preserve a firmer texture and bright green color. The process is something like the restaurant technique sous vide (French for “under vacuum”), where food is vacuum packed, then cooked in a water bath to ensure even heat. You can’t squeeze out all the air from a self-sealing plastic bag as with true sous vide, but this home adaptation still works well. You can find fresh nopales with spines removed at Hispanic markets, chain supermarkets located in Hispanic communities, or some specialty produce stores. The briny tartness of the vegetable escabeche (pickled vegetables) is balanced by the creaminess of the queso fresco, a slightly salty Mexican cheese that is similar in taste and texture to feta.
