Mix the flour, crumbs, finely chopped suet, and sugar in a basin, then stir in the jam. Beat up the egg and milk, and stir it in. Mix up the carbonate of soda and the vinegar together; beat it in, and when well mixed pour it into a buttered basin. Tie up carefully, and boil for two hours; turn out on to a hot dish, and serve either with sifted sugar or custard sauce.
Time: 2 hours.
