I think it’s good to get away from contemporary desserts – gelatines, contemporary flavours. This dessert has its origin in the Middle Ages, and began as a warm milk drink. Eventually it evolved into a dessert that was curdled, often with alcohol. There are other iterations where almonds and egg yolks have been used to thicken the milk or cream. In this recipe, though, the thickening agent is also the flavouring agent: lemon juice.
