How do you cut a round cake so it goes further?

In short

The way most of us cut a round cake, in triangles from the centre like a pizza, is precisely the one that yields least. The triangles come out enormous at the edge and tiny at the point, and halfway through there is nowhere left to cut.

How a pastry kitchen does it

In rings. Mark a circle about five centimetres in from the edge, and cut that outer ring into straight slices. When it runs out, mark another circle further in and repeat. The last centre piece is cut like a small cake.

Every slice comes out the same size, which is what lets a five-kilo cake actually serve fifty people.
