It is commonly believed that cutting a sandwich diagonally to create two triangles is the best way, but there is limited scientific evidence to support this claim.
One theory suggests that the triangular shape allows for the first two bites to be taken from a 45-degree corner, which has crust on only one side, making it easier to access the center of the sandwich where the filling is most concentrated.
After eating the corner, take 1-3 bites diagonally, missing the crust. Depending on the size of the sandwich, you may be left with an additional small triangle.
Ultimately, each triangle will become a single 90-degree chunk of crust. However, cutting the sandwich into rectangles would result in two crust corners on each half.
Another reason for cutting sandwiches into triangles is that they are easier to eat. Starting at one of the corners leads to a cleaner bite, and the 45-degree angle of the triangle maximizes the engagement depth.
If taken to the extreme, cutting the sandwich into four triangles allows for a neat eating experience in three bites.
This cutting strategy is often used at children’s parties, though kids might not always start with the 45-degree corner. In such cases, simply cutting off the crust altogether may be the best option.
