Swiss roll
A Swiss roll, jelly roll, roll cake, cream roll, roulade or Swiss log is a type of rolled sponge cake filled with whipped cream, jam, or icing. The origins of the term are unclear; in spite of the name "Swiss roll", the cake is believed to have originated elsewhere in Central Europe, possibly Austria. It appears to have been invented in the nineteenth century, along with Battenberg cake, doughnuts, and Victoria sponge. In the U.S., commercial versions of the cake are widely known under brand names like Ho Hos, Yodels, and Swiss Cake Rolls. A type of roll cake called Yule log is traditionally served at Christmas.
