Undergarments or the underside of something; in culinary terms, a base or foundation for a dish.
From French dessous meaning 'below' or 'underneath,' from de- and sous (under), borrowed into English from French cuisine and fashion terminology.
This French word is still used in fancy restaurants when chefs talk about the 'dessous' as the elegant foundation or base of a plated dish, keeping alive that French culinary vocabulary that makes cooking sound more sophisticated.
