Green beans are the unripe, young fruit of various cultivars of the common bean. Immature or young pods of the runner bean, yardlong bean, and hyacinth bean are used in a similar way. Green beans are known by many common names, including French beans, string beans, snap beans, snaps, and the French name haricot vert.
The pea is most commonly the small spherical seed or the seed-pod of the pod fruit Pisum sativum. Each pod contains several peas, which can be green or yellow. Botanically, pea pods are fruit, since they contain seeds and develop from the ovary of a flower.
The kidney bean is a variety of the common bean. It is named for its visual resemblance in shape and – for the red variety – colour to a human kidney. Red kidney beans should not be confused with other red beans, such as adzuki beans.
Puff pastry, also known as pâte feuilletée, is a flaky light pastry made from a laminated dough composed of dough (détrempe) and butter or other solid fat (beurrage). The butter is put inside the dough (or vice versa), making a paton which is repeatedly folded and rolled out before baking.
