I always have a problem preparing the right amount of batter for the number of pancakes I want to make. Some apparently very hungry math students from the University of Sheffield have swapped calculus for the kitchen and developed an interactive Perfect Pancake Calculator to make the prompt preparation of perfect prize-winning pancakes a piece of cake (alliteration!). You just enter the number and thickness of the pancakes you want and it gives you the exact amounts of the ingredients you need. One minor problem…Univ. of Sheffield is in England, so the measurements are metric!
