I appear to be on a bit of a cannellini bean trip at the moment - perhaps because my favourite brand of tinned beans, Cirio, have just become available again through Ocado. I will never be able to convince you that this is delicious by a photo, as it looks, well, like mushed up beans. But it DOES taste wonderful, and is a doddle to make. Nicer than bought hummus, and cheaper too. Drain and rinse a 400g tin of cannellini beans and tip into a food processor bowl. Ad a clove of garlic, crushed, the zest of a lemon, a tablespoon of lemon juice, a good grinding of pepper, a teaspoon of ground cumin, a teaspoon or so of fresh rosemary leaves, roughly chopped, and 2 tablespoons of good olive oil. Blend until smooth. Taste and add some salt and more lemon juice or olive oil if needed. Scrape into a bowl and serve as a dip or spread on toasted sourdough.
