According to mathematician Alex Bellos, most people are cutting their cakes incorrectly when they cut it in triangular pieces, like a pie-chart. But a better method for cutting cake has existed for over a century.
British mathematician Francis Galton wrote the letter "Cutting a Round Cake on Scientific Principles" to his editor, and was published in the scientific journal Nature in 1906. In order to cut a round cake perfectly, Galton recommends taking a round cake and cutting it directly down the middle.
"Christmas suggests cakes, and these the wish on my part to describe a method of cutting them that I have devised to my own amusement and satisfaction," Galton, clearly bored, wrote in the letter.
Cutting down the middle preserves the cake, while cutting the cake into triangular pieces dries it out. Here's how to best preserve a cake for its most flavorful taste.
