Salsa Romesco is Catalonia's answer to pesto—only more intense! This traditional sauce made from roasted bell peppers, tomatoes, and nuts becomes an absolute highlight when it meets sweet, smoky, burnt leeks. The secret lies in the roasting: 30 minutes at 200°C transforms simple ingredients into a velvety, nutty sauce with incredible depth. The leeks are deliberately charred until the outer layer turns black—beneath lies a buttery, sweet center. Blended with hazelnuts, red wine vinegar, and olive oil, the result is a sauce that goes well with everything: bread, pasta, grilled vegetables. By the way, it keeps for a week in the fridge—if it lasts that long! 🌿✨
