Thanks for all the replies.

Hello Melissa, welcome to the forum.  How long have you had your Thermomix or did you buy it in America?  Just wondering how you got on with the different electrical systems our countries have if you bought it from Australia.

I bought my thermomix in Australia 2 years ago and am running it on a transformer here in the US. So far I have just made my vegetable stock and it heated properly so am confident that it will work properly here.

Hi Melissa. What part of America are you in?

I am living in Florida

Hi Mama Mel - and welcome to the forum!

Have a look at this link - Helene, the superkitchenmachine lady, is in Canada.  She suggests using fresh whipping cream with a 33% fat content.

Hope this helps . .

Thanks for the link goldfish, that's exactly what I was after.  I have some super spatula's from Helene too.
