Tell me about it!! My daughter-in-law is from an Upper Midwest family that has a very bland flavor palate. It's only relatively recently that onions could become obvious in any dish. This has been an on-going project between my son and me to show her flavor does not equal death from overstimulation of the taste buds.
We once made our pasta carbonara without the onions to accommodate him. Never again. The onions stay in and he can just pick them out.
The entire onion family delivers great flavor.
