I cut them into small cubes (maybe 1/2 cm cubes), freeze them, then use them as I need to. I pick up a chorizo from the butcher once a month, and they go well in a lot of things. They're a very very good addition to pea and ham soup, or to omelettes etc. They're versatile, and if you cook them up and collect the oil (through a muslin) they give you a great cooking oil!
