From the 1881 Household Cyclopedia

Beat up the yolks and whites of 3 eggs, strain them through a sieve, and gradually add to them about a quarter of a pint of milk. Stir these well together. Mix in a mortar 2 ounces of moist sugar and as much grated nutmeg as will lie on a six pence; stir these into the eggs and milk; then put in 4 ounces of flour, and beat it into a smooth batter; stir in, gradually, 8 ounces of very fine chopped suet and 3 ounces of bread-crumbs. Mix all thoroughly together, at least half an hour before putting the pudding into the pot. Put it into an earthenware mould that is well buttered, and tie a pudding-cloth over it.
