Spanish Lentil Stew (Lentejas Estofadas)

Warm olive oil in a wide, heavy pot (at least 4L) over medium heat. Add chorizo slices and cook until the fat runs and the edges curl, about 3 minutes. Add onion and carrot. Cook, stirring occasionally, until the onion is completely translucent and the carrot is beginning to soften, 8–10 minutes. The oil should be stained deep orange from the chorizo.

Add minced garlic and cook 1 minute until fragrant. Add smoked paprika and cumin directly to the oil, stirring constantly. Cook for exactly 30–45 seconds — the spices toast in the fat, unlocking oil-soluble compounds. Do not let the paprika burn; it turns acrid instantly.

Add lentils and bay leaves, stir to coat in the spiced fat. Pour in water or stock and bring to a boil over high heat. Skim any foam that rises. Reduce heat to a gentle simmer — small lazy bubbles breaking the surface, not a rolling boil. Simmer uncovered for 25 minutes.

Add potato dice and season with salt. Continue to simmer for 20–25 minutes until potato is completely tender and the broth has thickened to a loose, cohesive stew consistency. Stir occasionally to prevent sticking. Remove bay leaves.

Off the heat, add sherry vinegar and stir through. Taste and adjust salt. The vinegar wakes up the smoked paprika and lifts the whole stew from heavy to vibrant. Let rest 5 minutes before serving — the stew continues to thicken as it cools slightly and is always better the next day.
