I have such stories about meatballs. Having grown up on a farm with family in the meat business, we always had top quality ground beef on hand. We made those things for everything! Just a pan full in the oven, and we went everywhere (not too many restaurants where we traveled and we often took road food with). A sandwich in one hand and even a cold meatball in the other, and that could keep the kids from whining. (Yeah, I was the eldest and had reponsibilities! ha!)
My family in law are Swedish, so, all they knew about meatballs was Swedish meatballs. For them, a meatball did not exist if it was not a Swedish meatball. So, the parents-in-law got older and I inherited the job of making Swedish food and of course, I had never seen a Swedish meatball. So, I just made some, and the family story went that I made the best Swedish meatballs ever! I just left those perceptions as it was too hard to change them. Those were African meatballs and they had never seen a Swede.
