Preheat oven to 160°C (320°F) then line a baking tray with baking paper. Butter 4 ring moulds of the same size (with no base) and place onto the tray.
Place butter, vanilla, salt, sugar, maple syrup, almond extract, and essential oils into the Thermomix bowl and mix; 6 min/Varoma/speed 1/MC off. Cool slightly.
Add cornflour, almond meal, and coconut and mix; 10 sec/speed 3.
Add almonds, pistachios, and craisins, and mix; 3 sec/speed 3. Scrape down the sides of the bowl and repeat until well incorporated.
Roll the mixture into small balls the size of a walnut. Refrigerate.
When it is chilled, cook 4 at a time by placing the balls into the prepared rings. Press down to flatten slightly. Cook for 6–8 minutes or until the cookies are well-spread and golden. If you want a more rustic look, you don’t need to use the rings.
Cool on a rack.
Pipe or drizzle the melted chocolate across the tops of the Florentines. Allow to set.
Use as sandwich cookies immediately after setting. Or store in an airtight container in the fridge until use.
