WARNING: Silpat, induction and wok do not mix!
Well I've been using a silpat between wok and stove as when I started out I didn't and wound up with some serious messes on the stove. But tonight I had a near-disaster. The Silpat (yes, the real thing not some off-brand) MELTED. Got goo all over the wok and some spots on the induction surface as well. Fortunately I was able to scrape and scrub it off but if I had not seen it in time it would have been awful.
I was using a basic flat-bottomed carbon steel wok (the one from Target - which BTW appears to have warped already) and the burner was on high (not power boost). Burner was on for maybe 2 minutes maximum - just enough to "cook off" the water. This does explain the odd discoloration, etc. I had been seeing with previous uses. Must have been little bits of it melting away.
I am so, so discouraged. This was the one thing that made me be at peace with having an induction stove rather than gas. Now I can't use that so I don't know what to do.
