Locro

Argentina's ancient Andean stew: corn, beans, squash, and pork, bound together by cumin

Origin: Tucumán, Argentina

From the journey of Cumin.

Locro is one of the oldest continuously eaten dishes in the Americas. Long before Spanish contact, the Quechua and Aymara peoples of the Andean highlands were making a thick, sustaining stew from the three pillars of their agricultural world: dried corn, dried beans, and the native squash of the high valleys. The dish was sustenance engineered for altitude and cold; slow-cooked until the corn split and the stew turned thick enough to hold a spoon upright, eaten from clay pots at elevations where the wind cuts through any lighter food. It was communal, practical, and ancient. When Spanish colonisers arrived in the 16th century, they brought with them the spices of the Old World: cumin, paprika, and the pork and fat that would transform the indigenous stew into something new. Cumin; native to the eastern Mediterranean and Central Asia, beloved in the Arab culinary tradition the Spanish had absorbed over seven centuries of coexistence; became the defining aromatic of the evolved dish. The Spanish also contributed the chorizo that now appears in virtually every version of the recipe and the chicharrón (fried pork skin and fat) that crowns a properly made locro. The result was not a replacement of the Andean original but a layering: indigenous structure, colonial spice, the whole greater than either part. Locro spread through the Andean northwest; Bolivia, northwestern Argentina (Tucumán, Salta, Jujuy, Catamarca), Peru; and is now formally recognised as Argentina's national dish. It is the ceremonial food of the patria: eaten on May 25th (the anniversary of the 1810 Revolution that began the independence process), on September 9th (Tucumán Independence Day), and on any other national holiday when communal feeding in the streets is both expected and politically resonant. On those mornings, hundreds of clay pots of locro are set to boil from before dawn in town squares, school courtyards, and community centres across the country, and the smell that drifts through Argentine streets; cumin, pork fat, sweet squash, wood smoke; is the smell of national identity made edible. The chicharrón topping and the salsa criolla: a raw sauce of spring onion, chilli, paprika, and olive oil; are served separately and added at the table, where they cut through the stew's considerable richness. Cumin is not optional in locro, and it is not background: it is the spice that converts a simple bean-and-corn porridge into one of the great stews of the world.

Ingredients

Stew Base

  • 300 g dried white hominy corn (maíz blanco / mote), soaked in cold water overnight and drained
  • 200 g dried white beans (cannellini or butter beans), soaked in cold water overnight and drained
  • 500 g pumpkin or butternut squash, peeled and cut into 3 cm cubes
  • 2 litres cold water or light chicken or pork stock

Meat

  • 400 g pork belly, skin on, cut into 3 cm cubes
  • 2 fresh or dried chorizo sausages, sliced into 1 cm rounds

Aromatics

  • 4 garlic cloves, finely chopped
  • 4 spring onions, white and green parts separated, finely sliced

Spices

  • 2 tsp ground cumin
  • 2 tsp smoked paprika (pimentón dulce)
  • 1 tsp ground turmeric

Seasoning

  • salt and freshly ground black pepper, to taste

Topping

  • 100 g lardons or chicharrón (pork scratchings), fried until crisp

Salsa Criolla

  • 4 spring onions, finely sliced
  • 1 red chilli, deseeded and finely chopped
  • 1 tsp smoked paprika
  • 3 tbsp extra-virgin olive oil
  • 1 tbsp red wine vinegar
  • salt, to taste

Method

  1. Drain the soaked hominy corn and rinse well. Place in a large, heavy-based pot (at least 5 litres) and cover with the cold water or stock. Bring to a boil over high heat, skim off any foam that rises, then reduce to a steady simmer. Cook uncovered for 1 hour.
  2. After 1 hour, drain the soaked white beans and add them to the pot with the corn. Continue simmering together for a further 45 minutes to 1 hour, until both the corn and beans are tender and the corn kernels are beginning to split and butterfly open. Add more water if needed to keep everything submerged.
  3. While the corn and beans cook, prepare the meat. Place the pork belly cubes in a wide frying pan over medium-high heat, skin-side down first. Fry without stirring for 4–5 minutes until the skin begins to blister and turn golden. Turn and brown on the other sides. The pork will render a significant amount of fat; do not drain this away.
  4. Add the sliced chorizo to the pan with the pork belly. Fry for 3–4 minutes until the chorizo is lightly browned and has released its paprika-stained oil into the pan.
  5. Push the meat to the edges of the pan and add the garlic and the white parts of the spring onions to the fat in the centre. Cook for 2 minutes, then add the ground cumin, smoked paprika, and turmeric directly to the fat. Stir and cook the spices in the fat for 2 full minutes, until they are fragrant and slightly darkened. This step, blooming the cumin and paprika in rendered pork fat, is the flavour foundation of the entire dish.
  6. Add the fried pork belly, chorizo, and all the spiced fat to the pot of corn and beans. Add the cubed squash. Stir to combine. The liquid should cover the solids by about 2 cm; add more water or stock if needed. Season generously with salt.
  7. Simmer the locro over low heat, uncovered or with the lid slightly ajar, for 1 to 1.5 hours, stirring every 20 minutes to prevent sticking on the base. The stew is ready when it is thick, creamy, and unctuous; it should coat the back of a spoon heavily and the corn should be completely soft.
  8. Make the salsa criolla: combine the sliced spring onions, red chilli, paprika, olive oil, and red wine vinegar in a small bowl. Season with salt, stir well, and set aside at room temperature. The salsa should be sharp, oily, and bright: a direct counterpoint to the richness of the stew.
  9. Fry the lardons or chicharrón in a small dry pan over high heat until deeply golden and very crisp. Drain on kitchen paper. Stir the green parts of the spring onions into the locro just before serving.
  10. Ladle the locro into deep, warmed bowls. Top each bowl with a scattering of crisp chicharrón and a generous spoonful of salsa criolla spooned directly over the stew. Serve immediately, with crusty bread alongside.

Notes

Dried hominy corn (maíz blanco pelado or mote) is available from Latin American grocery stores and many online retailers. It is not the same as polenta or masa; it is whole dried kernels that have been nixtamalised (treated with lime), and the long soaking and cooking time is non-negotiable. If hominy corn is unavailable, canned hominy (drained and rinsed) can be substituted; add it at the same time as the squash and reduce the total cooking time by about 45 minutes. Locro improves enormously the next day: the overnight rest deepens the cumin and allows the starch from the corn to fully integrate. Reheat gently with a splash of water, as it will thicken considerably in the refrigerator.
