Yes, it IS the Blancmange recipe! Actually, it's pretty good. I made it for my kids when they were younger. The term blancmange is derived from the Middle English blankmanger, from Old French blanc mangier : blanc, white (of Germanic origin) + mangier, to eat, food (from Latin manducare). Several medieval recipes for blancmange have survived, and the dish is mentioned in the prologue to Geoffrey Chaucer's Canterbury Tales.
