In my opinion everybody should draw the line at lima beans. And their sister butter beans. I hated them as a kid and I still do. I was told as a child I had to eat them and could not leave the table until I did. I hid a lot of them under the dining room rug.
I don't think I've ever had butter beans, but my parents were much the same about food. You have to eat what's provided and not leave the table until you do. I didn't like lima's, but Dad suggested adding ketchup to change the flavor. He didn't understand I wasn't a big fan of ketchup either, but it did help to improve the flavor of the lima's. But I've never eaten them since and hubs never liked them either, yet we both enjoy other types of beans. And anytime we have ham, it's assured ham & bean soup with cornbread will be in the near future.
IMO, ketchup only belongs on French fries and meatloaf.
