Stone fruit

Peach and peach pits

A stone fruit, also called a drupe, is a fruit with a large "stone" inside. The stone is sometimes called the seed, but that is a mistake, as the seed is inside the stone. The stones can also be called a pit. These fruits are edible and used frequently in cooking.

Identification

What makes a fruit?

A fruit is the matured ovary of a flower. Fruits consist of two main parts: the pericarp, or ovary wall, and the seed(s).

The pericarp has three layers: the exocarp (skin/rind), the mesocarp (bulk of the pericarp), and the endocarp (innermost layer).

Berries vs. drupes

The two main classes of fleshy fruits are berries and drupes, or stone fruits.

Berries have a fleshy mesocarp and endocarp, and may have multiple seeds.

Drupes have a fleshy mesocarp, but a tough endocarp, and of course, a "stone" or "pit" at its center. Drupes typically have only a single seed.
