All Enid Blyton's books featured this favourite tea time snack - the Famous Five and the Five Find Outers and dog loved it especially. This is made with clotted cream and strawberry jam. What is the snack?

Cream scones would seem to fit the answer-even though 'prepared' may be a better word than 'made'. They also had a thing about ginger beer.

Instead of romping home ravenous from an outdoor adventure to hot scones with lashings of cream and jam, a nineties version of Enid Blyton's Famous Five would perhaps trudge back from the CES office to find Mum's new boyfriend shooting up in the kitchen and the baby nursing bruises and a black eye.

Both Cornwall and Devon are famed for this delicacy. Traditionally this is made by pouring milk into shallow pans and leaving, undisturbed, for 24 hours allowing the cream to rise.

You can make your own clotted cream. Choose a wide, shallow earthenware pan. Strain very fresh (a cow is useful for this) milk into this and leave to stand, overnight if summertime or for twenty-four hours in cold weather. Then slowly, and without simmering, raise the temperature of the milk over a low heat until a solid ring starts to form around the edge. Without shaking the pan, very carefully remove it from the heat and leave overnight, or a little longer, in a cool place. The thick crust of cream can then be skimmed off the surface with a large spoon or a fish-slice.
