Some years ago, when silicon baking wares came out, I jumped on them with glee. No more scraping off baked on crud from the baking sheets! Muffins that popped right up with no greasing of the cups required! Easy washing up!
But these days I've definitely fallen out of love with silicon sheets and silicon muffin pans and the like.
About those muffin pans first: while muffins do brown on the outsides, they don't get as crispy-brown as I'd like. They also seem to rise a bit less than I'd like.
Also, they are totallly useless for popovers and Yorkshire puddings. You can't really heat them up, so you can't make them piping hot and pour in hot batter. The alternative method for making popovers 'pop' is to start them in a cold oven, but that doesn't work either. So I end up with flat, boring muffins of a sort, rather than high and airy pockets of trapped air and eggy, moist insides. Yes, I know I could just get separate pans for the popover and Yorkshire puddings, but I don't have that much storage space in my not-too-large kitchen, and I like to avoid 'single-use' type equipment as much as possible.
As for silicon baking sheets, used to line heavy baking sheets, they do okay on the browning front. But what I dislike about them is that, after a few uses they take on an unpleasantly 'greasy' feel to them. No amount of washing or soaking in soapy water seems to cure that. I don't know if I'm over-sensitive to this, but it drives me nuts. So I end up throwing them out over maybe 3 uses. This doesn't seem too economicalor environmentally friendly to me. (Do those things disintegrate at all in landfills?)
So, I'm back to good old metal baking tins and lining my baking sheets with kitchen parchment paper. My old metal muffin pans tend to stick a bit on the bottoms, so for delicate cupcakes and such I just use paper cupcake liners. (Which means of course I avoid those individual silicon cupcake cups.) Paper, at least, does disintegrate after a while.
How do you feel about those silicon baking products? Do you love them or hate them?
