Yes, you read that right. They’re perfect for melting butter on the grill for your clam cook-off! They should be placed off of direct heat (no open flames), as the silicone will char a bit if it gets too hot.
They can also be used to bake things in the oven like cupcakes and brownies. However, you should not broil them or put them on a burner directly.
And lastly, you can absolutely boil water in them. Perfect for making a poached egg while you’re camping or hot tea at home. Made from 100% food-grade silicone, they’re safe within temperatures ranging from -80̊ F to 450̊ F.
