CONTEXT: You may need to add more oil, say a generous tablespoon.

At least 8 cups for 1 pound of beans. <sep> Q: How do I stop the pressure cooker from clogging up when cooking lentils? A: be sure to use plenty of water. At least 8 cups for 1 pound of beans <sep> FOLLOWUP_Q: When I cook yellow lentils at home, the valve of the pressure cooker seems to clog up.### How do I prevent this?
