rondelle

Rondelle comes from French rond (round), from Latin rotundus. A rondelle is a small round thing — a round slice, a disc, a washer. In French cooking, a rondelle is a vegetable sliced crosswise into circles or half-circles. You take a carrot, a cucumber, or a zucchini, lay it on a cutting board, and cut across it. Every slice is a rondelle. The word elevates the most basic knife cut in existence to a term of art.

The rondelle is the first cut any cook learns, though they rarely learn the word. Every child who has helped a parent slice a carrot has made rondelles. The technique is so intuitive that it barely qualifies as a technique: hold the vegetable, cut across it, repeat. The thickness varies — 3mm for a garnish, 6mm for a sauté, 12mm for a braise — but the motion is identical. The rondelle is cooking's ground zero.

In French professional terminology, the rondelle has variants: the oblique cut (roll cut or tronçon), where the vegetable is rotated between cuts to produce angled pieces; and the paysanne (peasant cut), where the rondelle is halved, quartered, or cut into other flat shapes. Each variant has a name. Each name acknowledges that even the simplest cut can be modified, refined, and classified. The French professional kitchen names everything.

The word rondelle also appears in heraldry (a small disc on a coat of arms) and in architecture (a round ornamental panel). In each field, the word means the same thing: a small circle. The cooking rondelle, the heraldic rondelle, and the architectural rondelle are all named after the shape, and the shape is the oldest in human visual culture: the circle.
