As per pickle fans, the ridges in the pickle slices help them stay put on the sandwich amidst the pieces of meat, slippery slices of tomato or wet lettuce, and oily condiments.

Additionally, the crinkles in pickles create a nice crunch that adds depth to your sandwich’s texture since the other components, like bread and cheese, have a softer texture.

The ridges also help the pickle maintain its shape by providing strength and extra surface area, so they don’t become mushy in the center. They serve an aesthetic purpose as well.
