Ok so have just re-read it very carefully.  Weird how you interpret things (or maybe it's just me!!).  Realise we are getting food off the spatula and it doesn't have some other magic power to make the bowl become non-stick or something.  You know like clicking your heels together (Wizard of OZ).  Anyway thanks for clarification!

I have tried tapping on the inside of the bowl but didn't see any custard come off the side. 

Hi
Has anyone made potato flour and/or starch using thermomix?  I have looked at some recipes on the net but wonderedif Thermomix can give any shortcuts.
Thanks

I've called mine Betty because it is like having Betty Crocker in the Kitchen. 

Hi All
I have a customer who uses Thermomix for commercial use.  She regularly makes custard in double quantities.  She told me this works fine but she has then tried to make a second double quantity staright after the first and it does not thicken.  She does not completely clean the bowl inbetween so I suggested to try that.  I also thought it may be because the bowl is too hot and affects the thickening.  I am no chef or custard expert though so hope some of you may have some suggestions.
Thanks

Thanks to all for the welcome.  Townsville certainly is taking off, it is very exciting.  Hope to catch up with all the locals soon.
Cheers
