Simple Bean Soup from El Bulli (world's all time greatest restaurant!)

Step 1

Saute onion and herbs 8 minutes: Heat oil in a large heavy based pot over medium heat. Add garlic, onion, herbs and cook, stirring regularly, for 8 minutes until the onions are a deep golden brown and sweet.

Step 2

Cook tomato passata 8 minutes: Add tomato passata and cook over low heat for another 8 minutes until the tomato changes from red and watery to dark brown a d very thick. Don't skimp on this step, it's key for flavour!

Step 3

Simmer: Stir in the beans followed by the vegetable stock. Adjust heat so it's bubbling very gently and simmer for 15 minutes with the lid off.

Step 4

Blitz: Transfer 2/3 cup (150ml) of soup into a jug or jar large enough to fit the head of a blender stock. Blitz until smooth then stir it back into the soup to thicken the broth.

Step 5

Stir in Picada: Just before serving, stir in 2 tablespoons of Picada. Taste and add more salt if needed (canned beans differ in salt). Then serve immediately.

Step 6

Serve: Dollop each bowl with 1 teaspoon of remaining Picada. Crusty bread highly recommended (easy Artisan, no yeast bread or French brioche).

Step 7

Preheat a small skillet over medium heat. Add hazelnuts and toast, shaking the skillet regularly, until there are golden patches and they small nutty.

Step 8

Roughly chop then add into a jug just large enough to fit the head of a stick blender with remaining ingredients. Blitz until it's like pesto - not completely smooth. Use per recipe.
