Beat the eggs first, mix half the milk with them, stir in the flour and the rest of the milk by degrees, then the suet and raisins, and the moist sugar. Mix the eggs, sugar, and milk, well together in the beginning, and stir all the ingredients well together. A plum pudding should never boil less than five hours; longer will not hurt it. This quantity makes a large plain pudding: half might do.
