Hi all, this is only my 3rd day as a thermomix owner, everything is going well so far, I think, lol, but I do have one question,  Last night I made lasagne, and when I did the lasagne sauce everything seemed to be great, but when I poured it out of the jug there was a chunk of meat on each blade that had cooked solid.  It wasn't really a problem as such, because the rest of the sauce was great and it didn't ruin anything, I was just surprised to see it and was wondering if it was something that I did that caused this to happen, and whether I can avoid it next time, or if this is just normal...  Lol. 
Thanks in advance for any insight you can offer!
