The Pros and Cons of Baking With Silicone
Easy clean up: You can flip silicone inside out and get into those hard-to-reach corners. You can soak it without worrying that it's going to get rusty or damaged. This makes clean up a breeze!
Durable: Unlike metal, you don't have to worry about silicone developing rust over the years. Unlike glass, you don't have to worry about this material shattering if you drop it. Yes, it's an investment, but it's been worth it for me.
Space-saving: As mentioned earlier, silicone can be a huge space-saver. So, instead of having to have a barely used metal muffin pan banging around in your cupboard, you can have some soft, pretty silicone muffin cups that take up about the same space as a coffee cup!
Reusable and environmentally friendly: If you use a metal muffin pan, you've got to use those paper muffin cups—which will inevitably be thrown away. But with the silicone version, you eliminate the need for those paper cups, so you're creating less paper waste by doing so.
Safety research is spotty: This is exactly what it sounds like. There's not a lot of research out there about whether or not cooking silicone is safe. That means there's not a lot of "it's safe" or "it's not safe" literature. So, you'll have to decide for yourself! I personally think it's fine and quite enjoy cooking with it.
It can melt: Silicone isn't made to be used on direct heat sources such as a grill plate, a stove top, an open flame, or a broiler. Using it on one of these sources is really likely to melt it.
It can degrade: Some people, such as the SF Gate, have claimed that silicone can get punctured and degrade in other ways. My guess it that this has to do with the quality of silicone that you buy. Did you buy the stuff that turns white when you pinch it? It's probably going to bite the dust before a product that doesn't do that. Additionally, I don't really think the "degrading" is a con because nothing lasts forever! Glass shatters and metal rusts. No material is perfect.
