small jug of really good quality drinking chocolate
sugar, to taste
up a small jug of really good-quality drinking chocolate (I use
Charbonnel & Walker, which is quite expensive, but tastes
fantastic). Make some strong espresso. Third-fill two glasses with the
coffee, adding sugar to taste. Add another third of chocolate. Whisk
some single cream until frothy, pour over the mocha so that it sits on
the top. Drink and enjoy.
