Trucha EmpapeladaCooking foods in foil is very popular in Mexico, for both home cooks and chefs. Instead of the classic way of wrapping and steaming in corn husks or banana leaves, or leaves from the maguey plant, foil offers an alternative that's quicker and easier. The aromas and flavors of the real leaves may be missing, but foods cooked in foil are aromatic, juicy, and very delicious. Fish is exceptionally good cooked this way. Whole trout from a fish market are already cleaned and weigh about 1 pound.
Lay out 4 pieces of 12-inch-long foil, each large enough to completely wrap 1 fish.
Season each fish inside and out with salt.
Lay 1 fish in the center of each piece of foil.
Layer the tomatoes, onion, chiles, and epazote evenly among the fish.
Put 1 teaspoon butter on top of each.
Drizzle 1 teaspoon of wine over each fish.
Fold the foil over the fish and crimp the edges to make a snug package.
Put the 4 packages on a baking sheet and cook in the center of the oven 22 to 25 minutes, or until the fish is opaque inside and just barely flakes when tested with a fork.
