Dicing food is cut into small cubes, similar to the French brunoise cut. This can be done for presentation or to make pieces of the same size, so they cook evenly. Dicing helps spread the flavours and textures of a dish evenly and speeds up the cooking process.
Dice is a small cube with one to six numbers or spots on each side. It is used in games to come up with random numbers. In old-fashioned English, the word “dice” was only used as a plural, and the word “die” was used for the singular.
