Oh my gosh....we LOVE brussel sprouts! By we, I mean that includes my kids.
My son was really little and playing at a neighbor's house. I called to tell him he needed to come home in 15 minutes because dinner would be ready. He asked what we were having and when I mentioned brussel sprouts, he said, "Brussel sprouts? I'm coming home right now!" He said a hasty goodbye to the neighbor mom and ran out the door.
Another mom friend who was there visiting said she had never in her life seen a kid get so excited over brussel sprouts. In fact, she said she had never even seen a cooked brussel sprout in her life, let alone taste one.
I guess they are an acquired taste. Everyone in my family likes them.
We like them steamed with butter and garlic, but they are also good dipped in mayo or miracle whip. It cuts some of the tanginess. You might try that.
They are actually very good for you so I wouldn't give them up entirely because your family doesn't like them.
Best wishes.
