Katherine asked me how I make it. I don't measure anything, I've just done it often enough to be able to gauge from looking and tasting.
I soak some dried chickpeas overnight, then cook them for about an hour and a half, simmering in a pot of water. The I drain and rinse them, and blend them together with garlic, olive oil, lemon juice, some tahini, salt and paprika. I add some water to get the right consistency. In the serving dish I usually drizzle on extra olive oil and sprinkle more paprika and some chopped parsley. Sometimes I have also added extra things, like chopped black olives or spring onions. Short, sweet and simple.
