Still have trouble with my Ultra Grind+, the last batches was alright because I added cocoa butter, so the chocolate was enough fluid, then the wheels didn't have to much trouble to spin.
But I would like to make chocolate without adding any cocoa butter. So I'm facing the same problem, the wheels stopped again.
I runned the grinder with the liquor ( 1kg) until it was well fluid, and then I added the sugar on three laps of time, little by little. Waiting between each time to see the liquor getting enough fluid.
It was going well for an 1h30 and then one wheel stopped, so I took off half of the liquor and it started to spin again so I left it run during the night and when I woke up, not good!!!! both wheels were stock.
I wonder if the sugar could make the mix sticky, or maybe it start caramelise a little , but the temperature never go over 136F, so i don't think so.
Is it the me doing something wrong or is it necessary to have a bigger melanger to be able to make chocolate without cocoa butter?
