What is
Clabber is a food produced by allowing unpasteurized milk to turn sour at a specific humidity and temperature. Over time, the milk thickens or curdles into a yogurt-like substance with a strong, sour flavor.
Junket is a milk-based dessert, made with sweetened milk and rennet, the digestive enzyme which curdles milk. It might best be described as a custard or a very soft, sweetened cheese.
