Swiss roll is a type of sponge cake baked in a very shallow rectangular baking tray, and then filled, rolled up, and served in circular slices. You kight think the Swiss role is from Switzerland but the orgins are unclear.
Swiss Rolls are slightly different from jelly rolls or roulades; the sponge cake layer is thicker so it cannot be rolled as tightly. They look great, are inexpensive to make and although the recipes and hints are long, with a little practice they are quite simple to make. They always improve by sitting overnight before slicing, so plan ahead.
