Stone fruit

fleshy fruit with hard inner layer (endocarp or stone) surrounding the seed

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.

What makes a fruit? change

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 change

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.
