Method
Place the sorted pinto beans in a large bowl, cover with plenty of cold water, and soak at room temperature for 8 hours or overnight. Drain and rinse before cooking.
In a large heavy-bottomed pot, combine the soaked pinto beans, the intact half white onion, two whole garlic cloves, and 2000ml of cold water. Bring to a rapid boil at 100°C/212°F, then reduce the heat to low.
Cover the pot partially and simmer the beans until completely tender and creamy inside, about 1.5 to 2 hours. Do not add salt during this phase. Once tender, remove and discard the boiled onion and garlic cloves. Reserve the beans and all of their cooking liquid.
In a large cast iron skillet, melt the lard over medium heat. Add the finely diced onion and saute until translucent and lightly golden, about 5 minutes.
Add the minced garlic, ground cumin, and crushed Mexican oregano to the skillet. Toast the spices in the hot fat for 30 seconds until highly fragrant. Stir in the minced chipotles and adobo sauce.
Using a slotted spoon, transfer the cooked beans directly into the skillet. Pour in 250ml of the reserved bean cooking liquid. Bring the mixture to a gentle bubble.
Reduce heat to low. Using a bean masher, actively crush the beans in the skillet until you reach a thick, rustic puree. Add kosher salt to taste. If the mixture seems too dry, incrementally add more reserved bean cooking liquid, 50ml at a time, until you reach a soft, easily spreadable consistency.
Turn off the heat. Sprinkle the shredded Oaxaca cheese over the hot beans and gently fold it in until completely melted, creating luxurious cheese pulls. Transfer to a serving dish and garnish with an even layer of crumbled cotija cheese.
Chef's Notes
- Retain every drop of your bean cooking liquid. Often referred to as aquafaba, this starchy, flavorful broth is the secret to achieving a silky emulation when mashing the beans.
- While vegetable oil works in a pinch, high-quality rendered pork lard is fundamentally what gives authentic Sonoran refried beans their signature gloss, richness, and mouthfeel.
- Toasting the cumin and oregano briefly in the hot pork fat unlocks their fat-soluble flavor compounds, dispersing a deeply aromatic base throughout the entire dish.
- Do not salt the beans during the initial boiling phase. Salting early can toughen the skins and dramatically increase the cooking time.
Storage
Refrigerator: 5 days — Store in an airtight container. Press a piece of plastic wrap directly onto the surface to prevent a skin from forming.
Freezer: 3 months — Freeze in shallow, airtight containers. Thaw overnight in the refrigerator before reheating.
Reheating: Warm gently in a skillet over medium-low heat, adding a splash of water or milk to restore the creamy texture.
