Sofrito
The slow-cooked aromatic base — onion, garlic, pepper, tomato — that anchors Iberian, Caribbean, and Latin American cooking.
Traditions
The technique traces to medieval Andalusia and Catalonia (12th-13th century cookbook 'Libre de Sent Soví' has early references). Moorish-Iberian fusion of slow-cooked aromatic bases over olive oil. Spread to the Americas with conquest; in Puerto Rico and Cuba, sofrito became a freezer staple (recaíto) — every household has its own ratio. The Italian soffritto evolved separately from Roman ius-based broths.
What happens
Sofrito (Spanish), sofregit (Catalan), refogado (Portuguese), soffritto (Italian) — the same idea, the cooked-down aromatic base that flavors stews and rices throughout the Spanish-speaking world. Olive oil, finely chopped onion, garlic, sweet pepper, and often tomato simmered in oil until everything dissolves into a glistening jammy paste — 30-45 minutes of patient stirring at low heat. This is the foundation under paella, gumbo, ropa vieja, sancocho, and dozens of other dishes. Italian soffritto uses celery-carrot-onion (the Italian holy trinity) instead, with no pepper or tomato.
Mechanism
Slow gentle cooking (60-80°C oil temp) dehydrates aromatic vegetables without browning. Cell walls break, releasing flavor compounds (sulfur compounds in onion/garlic, capsaicinoids in pepper, glutamate in tomato) that mix into the oil — building a fat-soluble flavor reservoir. The long cooking time also concentrates flavors through water evaporation, producing a paste of intense umami-sweet-savory depth.
Practice
Heat 3-4 tbsp olive oil over LOW heat. Add finely diced onion (1 large), pinch of salt to draw out moisture. Stir occasionally for 10-15 min until translucent and soft. Add minced garlic (4-6 cloves), continue 2 min. Add finely diced bell pepper (1-2), cook 10 min. Add chopped tomato (2-3, peeled) or 2 tbsp tomato paste, cook 15-20 min until liquid evaporates and the mixture turns jammy. The sofrito is done when a wooden spoon dragged through it leaves a clean line. Failure modes: heat too high = browning instead of melting; too short = vegetables not soft enough; too dry pan = burning.
Lineage
Medieval Andalusian-Catalan → 13th-century Mediterranean cookbooks → Spanish colonial transplantation to Cuba/Puerto Rico/Mexico → modern Latin American kitchens. The Cuban variant uses ham and cilantro; the Puerto Rican recaíto adds culantro and ají dulce; Mexican variant uses chile poblano. Italian soffritto descends through Apicius (1st century Rome) → medieval brodi → modern Italian regional cooking.
Across cultures
Kinship
Mirepoix (French) is the celery-carrot-onion cousin. Roux (Cajun) adds flour to fat first, then sweats vegetables. Refogado (Portuguese) is closer to Spanish sofrito but uses bay leaf and pork fat. Tadka (Indian) is the spice-bloom counterpart — hot oil + whole spices instead of slow-cook vegetables.
