What is
Clotted cream (sometimes called scalded, clouted, Devonshire or Cornish cream) is a thick cream made by indirectly heating full-cream cow's milk using steam or a water bath and then leaving it in shallow pans to cool slowly. During this time, the cream content rises to the surface and forms "clots" or "clouts".
  
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.
