Like custard, the word dariole was, back in the early fifteenth century, the name o fa savoury pastry filled with meat; also like custard, the word dariole eventually shifted its sense and came to mean a sweet dessert made from milk, eggs, and sugar. Unlike custard, however, dariole shifted its sense once more as it became, in the early nineteenth century, the name of a small baking tin shaped rather like a flower pot. In origin, the word dariole derives from the French daurar, meaning to turn golden, a reference to the golden brown crust of the original meat-filled dariole.
