I was asking the question, to myself and others, how silicon would behave when roasting meats. This weekend, I did a small ham joint. It was cooked at 180C with a foil lid for one hour. Another 30 minutes without the foil. After the ham was removed, this was what remained in the container:
I have used the muffin pan to cook GF yorkshire puddings and they came out very well, without sticking. I always use a metal tray to stand the silicon dishes on otherwise they would be dangerous, with them being floppy!
