Natural release
Leave the release control sealed so the pot can cool and lose pressure on its own. The lid is ready to open only when the float valve drops. Follow your model’s directions.
Quick release
Use your model’s release control to vent only when the recipe and model instructions call for it. Keep hands and face away from the steam path. Never force the lid open.
Thick and starchy foods
Use natural release for thick, foamy, oily, or starchy foods when your manual calls for it. This includes many stews, chilis, pastas, and beans. If a vent spits liquid, return it to sealing only as your model directs and allow it to settle.
