Christmas cake is a centuries-old tradition. The majority of people who enjoy this festive treat may not know the science behind slicing it. A professor of mathematics and geometry tested the best way to cut a Christmas cake into slices. He focused on cutting it while leaving the insides as moist as possible. He said it is best to cut across the middle into two semicircles, then cut slices and push the remaining halves together.
Christmas cake is an English tradition. It is full of raisins, orange rind and other dried fruit. The fruit is often soaked in brandy. It is common to cover the fruitcake base in a layer of marzipan, then coat the top and sides in a one-centimetre layer of icing. People decorate the top of the cake with Christmas symbols like fir trees or snowmen and women. Christmas cakes vary around the world. In Japan, they are simple sponge cakes with whipped cream and strawberries.
