Preheat the oven to 180°C.
In a saucepan, melt the butter and sugar together over a medium heat until combined.
Put the granola, dried fruit and almonds into a mixing bowl and toss until evenly distributed.
Take the pan off the heat and stir in the salt and double cream, then pour onto the dry mix and stir thoroughly to coat the mixture.
Using a greased tart tray or muffin tray, spoon dollops of the mixture into each dent and press down firmly so you have a flat top, and to ensure they are compact. You should end up with about 25 florentines.
Bake in the oven for 10 minutes until golden brown in colour. Remove and leave to cool in the tray before transferring to a cooling rack using a palette knife.
When cool, melt the chocolate in a heatproof bowl over a pan of simmering water, stirring until completely liquid.
Dip the bottom of each florentine into the chocolate and transfer back to the cooling rack to set. At this stage you could add a pattern into the chocolate using a fork.
Leave to harden completely before serving.
Store in an airtight container.
