Junket (dessert) children, mostly due to its sweetness and ease of digestion. The same was true in the United Kingdom where, in medieval times, junket had been a food of the nobility made with cream, not milk, and flavoured with rosewater and spices as well as sugar. It started to fall from favour during the Tudor era, being replaced by syllabubs on fashionable banqueting tables and, by the 18th century, had become an everyday food sold in the streets. In the United States, junket is commonly made with a packaged mix of rennet and sweetener from a company eponymously known as Junket.
Rennet chymosin made by an animal, but is produced in a more efficient way. FPC products have been on the market since 1990 and, because the quantity needed per unit of milk can be standardized, are commercially viable alternatives to crude animal or plant rennets, as well as generally preferred to them. Originally created by biotechnology company Pfizer, FPC was the first artificially-produced enzyme to be registered and allowed by the US Food and Drug Administration. In 1999, about 60% of US hard cheeses were made with FPC, and it has up to 80% of the global market share for rennet.
