So... Over the weekend I was making a batch of swiss buttercream. I melted the sugar/eggwhites in the double boiler then transferred to the thermomix to whip. You're supposed to let the meringue cool to room temp before adding the butter, so I was watching the temp guage, and it dropped down to 37, then all of a sudden was back up to 50... I decided it was too warm in my house so put the bowl in the fridge to cool it down a bit, back into the thermomix to whip some more (has to get to stiff peak stage before adding butter, so about 10 minutes) and it was cool, then I look again and it's back up to 50!!! I realised that it was the blades heating up making the temp go up... This morning I was creaming some butter and sugar for muffins (butter was soft) and it only had to be on for a minute, yet in less than that time the 50 degree temp light was on again.
Is this 'normal'? Surely not?? It was a bit of a PITA, because it meant I had to get the old handheld mixer out to do my buttercream on the weekend, thank god I hadn't chucked it out yet!!
Any suggestions? I have no idea if the thermomix is heating up without the butterfly attachment, I have to admit I've been really slack using it lately...
