Pour the rum into a pan and heat gently on a medium heat, then set fire to it with a match (stand back!). As the flames begin to subside, add the cream and bring to a gentle simmer. Remove from the heat and stir in the butter and orange blossom water. Once the butter has melted, add a pinch of sea salt, then add broken chocolate, cover with a lid for 30 seconds, then stir. If the mixture splits, add a splash or two of boiling water. (I added 3!)

Pour your chocolate mixture in a medium sized bowl and refrigerate for 4 hours to set. Toast the nuts and then chop them up finely.

Scoop the chocolate mixture with a round spoon and form your truffle with another to give a rounded shape, then dunk the truffle in chopped nuts or cocoa powder. Alternatively, you can dip your truffles into melted chocolate!

Keep prepared truffles refrigerated in an airtight container.
