Cream butter with icing sugar and the vanilla pulp. Finely grate the chocolate. Mix with rum, lemon juice and 60 g grated coconut into the butter. Use a teaspoon to cut off approx. 30 piles from the truffle mixture.
Squeeze in an almond at a time and form the piles into balls with cool hands. Turn into the remaining 40 g of grated coconut. Keep the truffles in a cool place.
