Pouring or Whipping Cream: has a fat content around 35% - sometimes simply called Fresh Cream.
Double Cream: has a fat content of 45%. Luckily, there are quite a few on the market in Australia now.
Thickened Cream: pouring or whipping cream to which gelatine has been added. It can be used instead of thick cream, but do try to get the real thing.
Clotted Cream: has a fat content up to 65%. Very rich and yummy. It has that distinctive clotted layer on top. Serve in all its glory at the table.
