When cutting a circular cake, the go-to move is cutting it in a triangle, right?

Instead of cutting your cake into triangular pieces, you need to cut it directly down the middle.

“You’re not maximising the amount of gastronomic pleasure you can make from this cake,” Alex revealed.

He then revealed that the proper way to cut cake was discovered around 100 years ago and showed a science magazine that gave notes as to how best to cut a round cake.

So to preserve that delicious cake you won’t manage to eat in one day, you are supposed to cut a slice through the middle, which creates square slices.

You then push the cake together, wrap an elastic band around the cake and put it in the fridge, so that the next day the cake is still fresh and you can repeat the process until all the cake is gone.
