- Prepare lentils: Rinse 1 cup lentils in a fine-mesh strainer, removing any debris or shriveled pieces. Do not skip rinsing, as it removes dust and potential impurities.

- Season wisely: Add aromatics like 1 chopped onion, 2 minced garlic cloves, or 1 bay leaf. Avoid adding salt until after cooking, as it can toughen lentils during pressure cooking.
- Set cooking time: Close lid, set valve to sealing position. Select Manual/Pressure Cook mode:
- Brown/Green: 12 minutes high pressure
- Red/Yellow: 7 minutes high pressure
- Black/Puy: 14 minutes high pressure
- Pressure release: After cooking completes, allow 10 minutes of natural pressure release before carefully turning the valve to venting position. This gradual release prevents lentils from becoming mushy.
