Subtlety

An entremet or entremets (/ˈɑːntrəmeɪ/; French: [ɑ̃tʁəmɛ]; from Old French, literally meaning "between servings") is in modern French cuisine a small dish served between courses or simply a dessert. Originally it was an elaborate form of entertainment dish common among the nobility and upper middle class in Europe during the later part of the Middle Ages and the early modern period. An entremet marked the end of a serving of courses and could be anything from a simple frumenty (a type of wheat porridge) that was brightly colored and flavored with exotic and expensive spices to elaborate models of castles complete with wine fountains, musicians, and food modeled into allegorical scenes. By the end of the Middle Ages, it had evolved almost entirely into dinner entertainment in the form of inedible ornaments or acted performances, often packed with symbolism of power and regality. In English it was more commonly known as a subtlety (also sotelty or soteltie) and did not include acted entertainment.

For modern pastry chefs, an entremet is a multi-layered mousse-based cake with various complementary flavors and varying textural contrasts.

Dishes that were intended to be eaten as well as entertain can be traced back at least to the early Roman Empire. In his Satyricon, the Roman writer Petronius describes a dish consisting of a rabbit dressed to look like the mythical horse Pegasus. The function of the entremet was to mark the end of a course, met (a serving of several dishes), of which there could be several at a banquet. It punctuated each stage of a banquet, prepared the diners for the next serving and functioned as a conversation piece. The earliest recipe for an entremet can be found in an edition of Le Viandier, a medieval recipe collection from the early 14th century. It described a comparatively simple dish: boiled and fried chicken liver with chopped giblet, ground ginger, cinnamon, cloves, wine, verjuice, beef bouillon and egg yolks, served with cinnamon on top, and was supposed to be of a bright yellow color. An even simpler dish, like millet boiled in milk and seasoned with saffron, was also considered to be an entremet.
