Smoky, nutty, red-pepper backbone of a Catalan feast.
Born in Tarragona for the fishermen's calçotada, romesco is charred red peppers, ñora chilli, almonds, hazelnuts, garlic and stale bread — pounded into a rust-red paste that tastes like a bonfire in the best sense.
Char 2 red peppers and 2 vine tomatoes under a grill until blackened. Peel and deseed.
Toast 60g almonds + 60g hazelnuts in a dry pan until fragrant. Rub the hazelnut skins off.
In a food processor, pulse the peppers, tomatoes, nuts, 2 garlic cloves, a chunk of toasted stale bread and 1 tsp smoked paprika.
Stream in 100ml olive oil and 2 tbsp sherry vinegar. Season. Pulse — leave it slightly nubbly, never smooth.
