Prepare pickle day before. Place sugar, vinegar, miso and 180ml water in a medium saucepan with one 1 teaspoon of salt. Bring to boil, pour into heatproof, non-reactive bowl containing the mushrooms, onion, both types of peppercorn, allspice and bay leaves. Leave to cool, cover and refrigerate overnight.

Drain the beans, put in a food processor, along with the tahini, 4 tablespoons of the olive oil, the garlic, lemon juice, 3/4 teaspoons of salt and 1/2 teaspoon of white pepper. Blitz well until a very smooth paste has formed and set aside. Once ready to serve, add a little cooking liquid if you need to get a soft and fluffy consistency.

Pour the remaining 40ml of olive oil and all of the sunflower oil into a frying pan and place on a high heat. When hot, add the pitta and fry for about 3 minutes, shaking the pan from time to time until golden and crisp all over. Transfer to a colander lined with kitchen paper sprinkle with a pink of salt
