I'm so glad oxtails are back in British supermarkets, after the mad cow scares. This is by my daughter's request. She's always turned her nose up at it but after having it at a friend's house, loves it. The recipe comes from Mrs Beeton's Family Cookbook. After browning the meat and onions,I bung it in the slow cooker and leave it on all day. Serve with mashed potatoes and veg.
