Cucumber
Cucumber is the immature fruit of Cucumis sativus, a cultivated plant in the gourd family. It is eaten fresh, cooked, or preserved by pickling.
Cucumis sativus: A flowering vine species cultivated for cucumbers, native to South Asia. This is the species whose immature fruit is eaten as cucumber.
Pickling: Food preservation by immersing ingredients in an acidic brine or fermenting them in saltwater. Pickling extends cucumber shelf life and produces familiar sour or fermented forms.
Domestication of plants: The process by which humans cultivate and genetically alter wild plants across generations. Cucumber cultivation transformed a wild South Asian plant into a globally familiar crop.
Zucchini: The immature fruit of a cultivated summer squash, usually eaten cooked or raw. Zucchini is another immature cucurbit fruit, but it belongs to a different species and is usually cooked.
Cucurbitaceae: A flowering-plant family that includes gourds, melons, squashes, and cucumbers. Cucumber belongs to this family, whose fruits share distinctive growth and structure.
Fermentation: The microbial conversion of sugars into other substances, often acids, gases, or alcohol. Lactic acid fermentation preserves cucumbers and gives some pickles their characteristic tang.
South Asia: A region of Asia that includes the Indian subcontinent and neighboring countries. Cucumber’s domestication is traced to this region.
Pickled cucumber: A cucumber preserved in vinegar or fermented brine. Preservation changes cucumber’s flavor, texture, and storage life.
Berry: A fleshy fruit that develops from one ovary and usually contains seeds embedded in pulp. Botanically, cucumber is a type of berry despite its everyday classification as a vegetable.
Tzatziki: A Greek and southeastern European sauce made chiefly from yogurt, cucumber, garlic, and herbs. Grated cucumber contributes its cool flavor and moisture to this sauce.
