"This is one of the most delicious Catalan traditions. Starting around February and going until April, you can enjoy a specialty dish celebrating the spring onion: giant, charcoal-grilled spring onions, dipped in Romesco sauce, and served upside down (per tradition). You’ll have to wear a bib because things get messy quickly. The meal is accompanied by ample amounts of wine, drunk straight from a special jug. You can either stay in town and have the dish at one of the squares in Gràcia or go to Can Carbonell, a great restaurant outside of town that local celebrities visit to get sloppy with some onions." - MATADOR_NETWORK
