Aguascalentense Roasted Suckling Pig (Lechon al Horno)

Ingredients

Equipment Needed

• •Large roasting pan fitted with a sturdy rack
• •Cast iron comal for toasting chiles and spices
• •High-powered blender
• •Fine-mesh strainer
• •Instant-read thermometer
• •Pastry brush for melted lard
• •Large terracotta serving platter

Instructions

1. 1

   Salt the pig

   Pat the suckling pig completely dry, inside and outside. Rub it with 2 tablespoons kosher salt and the black pepper, working into the belly cavity, shoulders, hams, and behind the ears. Set it on a rack over a sheet pan and refrigerate uncovered for at least 8 hours, preferably overnight. Dry skin becomes crisp skin. Wet skin stays stubborn.

2. 2

   Toast the chiles

   Heat a dry comal over medium. Toast the guajillo chiles 20 to 30 seconds per side, just until they brighten and smell fruity. Toast the ancho and pasilla separately because they burn faster. Do not let them blacken. Burned chile turns bitter and then the whole pig carries your mistake.

   Guajillo is the face of this adobo. Buy chiles that are flexible and glossy, not brittle and dusty. If the chile cracks like old paper, leave it at the stall.
3. 3

   Soak and grind

   Put the toasted chiles in a bowl and cover with hot water for 20 minutes. Hot water, not boiling. While they soften, toast the cumin, cloves, canela, and allspice on the comal until fragrant, then grind them. Drain the chiles, saving the soaking liquid. Blend the chiles with garlic, onion, Mexican oregano, ground spices, crumbled bay leaves, vinegar, orange juice, lime juice, melted lard, piloncillo, and 1 cup soaking liquid until absolutely smooth.

4. 4

   Strain the adobo

   Push the adobo through a fine-mesh strainer into a bowl, pressing hard on the chile skins. Taste it. It should be red, deep, lightly sweet, aromatic from clove and canela, and salty enough to season a whole animal. Stir in the remaining 1 tablespoon salt. If it tastes shy now, it will taste shy after eight hours in the oven.

5. 5

   Rub and rest

   Use a small sharp knife to make shallow slits in the thickest parts of the shoulders and hams without tearing the skin. Rub the adobo all over the pig and into those cuts. Rub the belly cavity well. Keep the skin side mostly clean of thick chile paste, because chile paste on the surface can burn before the meat is tender. Refrigerate uncovered 12 to 24 hours. This is a two-day dish. Así se hace y punto.

6. 6

   Build the roasting bed

   Take the pig out of the refrigerator 1 hour before roasting. Heat the oven to 250F. Scatter the potatoes, carrots, sliced onions, halved garlic heads, and bay leaves in a large roasting pan. Pour in the water or light pork stock. Set a rack over the vegetables and lay the pig belly-down or slightly on its side, tucking the legs naturally so the skin is exposed and not pressed flat.

7. 7

   Roast low

   Roast at 250F for 6 to 7 hours, basting the meatier exposed areas with pan juices every hour and rotating the pan once if your oven has hot spots. Add a little water if the pan dries out. The pig is ready for the final heat when a thermometer reads at least 160F near the shoulder and ham, and closer to 180F if you want meat that pulls easily from the bone. The joints should loosen when you move a leg.

8. 8

   Crisp the skin

   Raise the oven to 450F. Brush the skin with the remaining 1/4 cup melted lard and sprinkle lightly with salt. Roast 20 to 35 minutes more, watching carefully, until the skin blisters, tightens, and turns deep mahogany in patches. If one area browns too fast, shield it with foil. The sound you want under the knife is a clean crackle, not a soft tear.

9. 9

   Rest and serve

   Rest the pig 25 to 30 minutes before carving. Spoon the roasted potatoes, carrots, onions, and garlic onto a warm terracotta platter and set the carved lechon over them with pieces of crisp skin on top. Serve with warm corn tortillas, salsa de chile seco or guajillo, pickled red onion, and lime wedges. The table should be practical: meat, tortillas, salsa, hands. Saber cocinar es saber vivir.

Chef Tips

• •Ask a Mexican butcher or a serious carniceria for a 12 to 15 pound suckling pig. Larger pigs need a different roasting plan. This recipe is for lechon, not a full market hog.
• •The adobo should be guajillo-forward. Ancho supports it. Pasilla darkens it. Do not replace the chiles with generic chili powder. That is not a shortcut, that is surrender.
• •Keep thick adobo off the skin during roasting. Put the flavor under and inside. The skin needs dryness, lard, salt, and hard heat at the end.
• •If your oven cannot hold a whole pig, ask the butcher to split it lengthwise. Roast the halves skin-side up on racks. The flavor stays right, even if the presentation loses the feria drama.
• •Serve this with corn tortillas, not flour tortillas, and no cheddar, sour cream, or lettuce. This is Aguascalientes, not a costume party.

Advance Preparation

• •The chiles can be toasted and the dry spices measured one day before blending the adobo.
• •The adobo can be made up to 3 days ahead and refrigerated. Warm it slightly before rubbing so the lard loosens.
• •The pig should be salted the night before and rubbed with adobo 12 to 24 hours before roasting.
• •Leftover lechon keeps refrigerated for 3 days. Reheat the meat covered at 325F with a spoonful of pan juices, then crisp the skin separately in a hot oven.
