A marrow is a vegetable, the mature fruit of certain "Cucurbita pepo" cultivars. The immature fruit of the same or similar cultivars is called "courgette" (in Britain, Ireland, France, the Netherlands, Singapore, Malaysia and New Zealand) or "zucchini" (in North America, Japan, Australia, Czechia, Italy, Germany and Austria). Like courgettes, marrows are oblong, green squash, but marrows have a firm rind and a neutral flavour ("overgrown when picked and insipid when cooked"), making them useful as edible casings for mincemeat and other stuffings. They can be stored for several weeks after harvest (like pumpkins and other winter squash), to be processed for food when required. They are a vegetable used in Great Britain and areas with significant British influence, though their popularity is waning in favor of immature summer squash like courgette.
