I made the black bean soup from Cook's Illustrated. It's really good except for an onion overtone because I didn't brown the onions enough. Stupid me, I forgot to taste it along the way. Bean soup + oniony flavor = lots of smelly farts!
Simmering doesn't seem to work and I want to eat the rest, but I don't know if my roommate could handle that, LOL!
Any suggestions on how to fix it?
