In baking layer-cakes it is important to thoroughly grease the tins - to make it emphatic, we will say thoroughly grease and then grease again - and after using rub off with a coarse towel, taking care that they are perfectly free from all small particles of cake, grease and fill again, thus obviating the necessity of washing every time they are filled. If jelly is used to spread between the layers, it is a good plan to beat it smoothly and spread it before the cakes are quite cool. In "building," an inverted jelly-tin furnishes a perfectly level surface on which to lay and spread the cake, and it may be allowed to remain on it until perfectly cold, when it should be set away in a tin cake-box, in a cool place. In cutting, it is better to first make a round hole in the center, with a knife, or a tin tube, about an inch and a quarter in diameter. This prevents the edge of the cake from crumbling in cutting. In making the custard or "filling" for layer-cake, place in a custard-kettle or in a tin pail. Set in boiling water to cook, to avoid all danger of burning.
