Interesting. I wonder if the cinnamon will be bitter against the lactic cheese, and would mixing sugar with it like a donut dusting give a better result?
Adding Allspice (pimento) and ginger would give the Christmas spice effect if the cheese is sweet enough to balance the spice.
Vanilla extract might work in the pack, but I would have suggested using a split bean in your milk after scraping in the seeds. They would have given the cheese a slight dusting of little speckles, and the flavour from the seeds would have been a lot more persistent.
I have experiments in the fridge with Honey and Ginger, Coffee crust, Chocolate crust, Sweet Chilli, Balsamic Vinegar and a few more I have forgotten. This was basically to see which flavours would persist and penetrate in the bag, and which complimented the cheeses (mainly Gouda based). We should pool resources
