What is
Dulce de leche is a confection prepared by slowly heating sweetened milk to create a substance that derives its taste from the Maillard reaction, changing flavour and colour.
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".
