banoffi pie (banoffee pie) a dessert made from biscuits, butter, cream, bananas, and condensed milk (dulce de leche). Its name is a portmanteau, a combination of banana and toffee. Two chefs from the Hungry Monk restaurant in Jevington, E. Sussex, claim to have invented it in 1972. The dish gained remarkable currency in English country restaurants within a few years, appealing to the sweet tooth of a new generation of diners. The recipe was never patented, however, and in the 1990s a number of supermarkets began selling it as American pie.
