Used a sweeter Calvados (Chateau de Breuil Fine) and it was quite good, if a bit sweet. Should just reduce the syrup to around 7.5. I will say that I used 45ml Calvados and 15 Rye to make it make more sense from an ABV perspective.
Just splitted the syrup, adding a bsp of maple syrup to bsp of 2:1 cinnamon syrup. It opened the Calvados really well. For garnish used a gold pear fan. It was amazing.
