Please don't use your blender to purée food you've cooked in a non stick saucepan.
I made a batch of food for my ds2 at my mum's house using her (scratched) non stick saucepan, and whilst putting it all in individual food pots noticed lots of black bits. It was the Teflon from her pan. Had to chuck the whole lot.
Then today, made exactly the same mistake at my house. Just cooked some chicken and veg and stock in my non stick saucepan, blended it, and then potting it all up saw all the bastard bits of black!
Yes, I know I'm thick for making the same mistake twice, but it is so frickin annoying that I want to save you all the bother of buying, peeling, chopping and cooking for absolutely no gain at all but the massive urge to scream!
I have chucked my pan. And want a lovely new set of stainless steel pans for Christmas. Really want le Creuset actually but budget ain't gonna stretch that far.
How irritating. If you're looking for stainless steel pans I can recommend Harts of Stur - www.hartsofstur.com They have a good price for Stellar stainless steel and Judge Vista stainless steel pans (I have Stellar pans which are great and cheaper than Le Creuset!)
