Put the gelatine in the stock, and heat just until it dissolves. Put all the ingredients in the food processor, having first skinned the chorizo and chopped it in chunks. The mixture should not be blended too smooth; in fact, the whole thing can be made by hand, mashing the beans, finely chopping the other ingredients, and mixing in the stock and gelatine.
