Warm half of the cream in a saucepan until hot but not boiling
Meanwhile, place the finely chopped chocolate into a heatproof jug
Pour the hot cream over the chocolate, let sit for 30 seconds to allow it to melt, then beat with a mini balloon whisk until smooth
Mix in the condensed milk, followed by the remaining cream
Add the cherry brandy and brandy, stir well
Optional step: to thin the drink stir in the milk
Strain through a piece of muslin or a nut bag to ensure the final drink is smooth
Decant into a sealable bottle and store in the fridge for up to 1 month
Shake the bottle vigorously before pouring to re-blend any chocolate that has settled back into the drink
