My Mom was a great cook. Only problem was getting her to cook. I'd be the one pestering her to get up and start. I'd then stand there mainly to make sure she didn't quit. Now I'm a pretty good cook myself. She did figure out what foods us boys refused to eat.
Now the only things I wouldn't eat, was Garbanzo beans, or Liver. She cooked them for my Dad. Both have a funky, grainy texture.
Dad liked cow tongue, too. Mom would pressure cook it with onions and celery, then peel the skin off. I like it cold, with mustard on a deli plate. It's tender that way, and like fine grain roast beef. A whole tongue cost as much as two thick Ribeye Steaks now days.
