For the Pudding, Andrew Aquino, with Russell Samora and Jan Diehm, supplies interactive graphics to show the many ways to cut an onion for an even dice.
An onion has a spherical shape with layers, where the outer most layer has more surface area than the inner most layer. If an onion were just flat like a layer cake, you could cut straight down in a grid pattern and you’d get even cuts. But it’s tricker with a sphere, and you want even cuts for an even cook.
Be confused no more.
Usage of an onion font for titles is also very fitting.
