Most people cut a rectangular sandwich diagonally into two triangles. But is that really the best way?
Researcher Luis Villazon talked to Science Focus about the perfect way to cut a sandwich.
Villazon’s argument: cutting into triangles makes the first two bites come from the corners at a 45° angle. Those bites have crust on only one side and give quicker access to the sandwich’s center, where most of the filling is concentrated.
Once you’ve tackled the corners, you’ll have one to three bites left along the diagonal, which has no crust. Depending on the sandwich’s size, you might even be left with a smaller triangle.
Eventually each triangle leaves you with a single crusty corner at a 90° angle. If you cut the sandwich straight instead, each piece ends up with two crunchy corners rather than just one.
Another argument for triangles is that they’re easier to eat. Kids and cartoon characters often ignore that and bite into the middle, smearing mayo or jam all over their faces. Start at a corner and the bite will be cleaner.
Experts recommend cutting the sandwich into four triangles and eating each one in a few neat bites.
Children’s party organizers also favor this method and often trim the crusts. Still, kids rarely begin eating at a 45° corner.
