Cool Tools reviewed these cool food-grade silicone bowls and cups from Guyot Designs.
They can be baked, boiled and frozen without ill effect... Guyot’s bowls are entirely pliable, and eating out of a bowl without structural rigidity can be a strange experience the first time. Their flexing and bulging when holding liquids does take some getting used to. But I’ve never had a problem eating out of them. This amorphousness comes in handy when you want to slurp back the rest of your milk or finish off the end of your camp stew, as you can squish the side of the bowl into a convenient spout.Cool Tools
