Growing up I hated celery. My mother loved it, and would put it in salads, stews, and even mash potato. When I left home, I left it off the shopping list until just recently, when I thought, "I'll give another go". Now I love it! Especially with mashed potato and chives. I've also gone off chocolate! How have your taste changed
I used to love sweet rice growing up but I slowly got tired of it. I was going to say I don't eat most fast food around here anymore but I don't know if that's my taste changing so much as the quality of the food. I'm not sure how my tastes have changed other than that but I do know that I'm more open to trying new things than before.
I think the only way my tastes have changed really revolves around eating everything on the face of the planet now regardless of how crazy/bizarre/scary. I, likely, would not have done that as a child. Also, I cannot stand ketchup. That's the one thing I will not eat. It's the devil's condiment. It ruins meals/sandwiches/HOT DOGS (UGGGGGGH drives me crazy).
