A firm favourite over the age, this cake proves ever-pop.
Delightfully simple to devise - no preparation! - it makes a lovely
dessert at any time of the yr, and especially for picnics.

Work the butter or margarine with the cocoa, and mix in the biscuit
crumbs. Mix the sugar with a little water and dissolve it over a low
rut, stirring. Then bring to the boil and simmer until viscous -
around 3-4 transactions. Blend into the cocoa mixture. Stir in the egg,
then fold in the biscuits broken into bite-sized pieces. Put into an
oiled loaf tin and chill until set. Turn out when completely cold and
service sliced, with cr?me fraiche.
