REPORT ON USING NON-HC CHOCOLATE
Just tried using some chocolate bars.
The "beater spring" looks very fragile, so whatever you use has to be very finely grated to avoid damage. Also, because it may have a higher melting point than HC choc, Youtube videos suggest heating the milk a bit first in the machine before sprinkling it in.
I first tried a 150g bar of Lidl chilli choc. I broke up the squares into smaller pieces, then put into my Kuhn-Rikon pull-chop to break it up finer.
This took ages, and really gave me muscle ache, and yet it still had lumps which were far too big for the Velvetiser, as well as some fine powder.
So I only used the powder parts and this worked OK, then I put the rest into my Bullet-type machine (Ninja auto-IQ) and this seemed OK, but it was less than 100g.
It tasted fine, although I haven't tried the HC chilli yet to compare.
Next I put 2x150g bars of Lidl sea salt choc into the Ninja, thinking I'd make a large batch at once.
This was a bit of a disaster. It ground it up OK, but then it jammed up around the blades, and "joined back together again" so it took ages to scrape it off the blades, and it was still lumpy as it had joined back together into soft lumps. Perhaps the machine had melted it a bit by friction.
So I put this into a container, then had to chop the lumps back into a powder. Then I made a drink with 35g, but this time the machine made a loud noise after 30 seconds. Couldn't see any reason tor it, and after removing and replacing the whizzer, it was OK.
The drink was fine, but I haven't yet tried the HC equivalent.
So It seems I will have to actually GRATE the chocolate manually, which I was trying to avoid as I dislike grating anything.
As I said, the "whizzer spring" does look very delicate, so I don't know how long it will last. You have to be very gentle cleaning it, and try to avoid touching it.
