Make a layer of Genoese, or of sponge-cake No. 1. Put the mixture on the layer tins in spoonfuls, placing it around the edges; then with a broad knife smooth it over toward the middle, making it as even as possible. Another way is to press it through a pastry bag in lines onto the tins. The layers should be only one half inch thick when baked, and the crust should not be hard. As soon as it is removed from the oven, and before it has had time to cool, cut off the hard edges, spread it with currant, or any jelly or jam, and roll it up evenly; then roll it in a paper and tie, so it will cool in a round, even shape.
