In a double saucepan (or a Pyrex bowl in a saucepan), place chocolate, butter and cream. Heat through slowly until smooth whilst whisking. Remove from heat and divide into 5 equal portions, adding the various flavourings to each individual portion. Leave to set, either in a fridge for a couple of hours or on the counter overnight. Don’t leave them in the fridge too long or you won’t be able to mold them.
