I first came across the idea of red kidney beans in damson sauce in Rose Elliot's "The Bean Book". I've since discovered that Rose's recipe is based on a Russian dish called Lobio. I've made a few tweaks to Rose's recipe, including making it more 'instant' by using canned kidney beans. Traditionally you're supposed to serve this dish cold, but we can rarely manage to wait that long (I did say "rushin") so I serve it hot as a main dish, over baked potatoes; usually with salad and coleslaw. If you can wait, this is lovely served cold as intended. I use my own home made jam in this recipe (Damson Jam Recipe #139722) but if you can't find damson jam, plum jam can be substituted (warning: plum jam is sweeter so I suggest starting off with a smaller amount and adding to taste). Serves 2 as a main dish, 4 as a side dish.
