Junket is a company that made prepackaged powdered dessert mixes and ingredients for making various curdled, milk-based foods, such as rennet custard, ice cream and rennet tablets. In 1874, Christian Hansen founded Hansen's Laboratorium in Denmark to make rennet extract for the cheesemaking industry. Later in 1878, he opened up operations in the United States. Herkimer County, New York, was chosen for the headquarters, since it was the center of the US cheese industry at that time.
Rennet tablets, commonly referred to as "Junket tablets", are a common source of rennet for home cheesemakers.
The "Junket" brand is now owned and used by Redco Foods.
