A woman in my congregation who is an Orthodox convert is from Iowa. She told a great story about being at a meeting with a group of rabbis. A man who worked for a kosher food producer on “new products” had brought some very tasty snacks for people to try. He was especially proud of a new meat product and my friend K agreed that it was delicious. He was sure that no one would be able to figure out what flavorings were used to create such a great taste. K said that she thought it was “honey smoked” and she was right. The man wanted to know how she knew and she explained that it tasted just like honey smoked ham. Then she watched with amusement as the other people who had been enjoying the snack looked uncomfortable and some even pushed their uneaten meat away from themselves! Just the thought that it might taste like a pork product made it unpalatable to these very observant Jews.
A flip side story was when we lived in Israel for a summer and when my mother was visiting we went over to the home of an Orthodox friend. He was very excited to get my mother’s opinion on whether the kosher fake crab he had tasted like real crab. I thought it was very respectful of him that he never even considered asking me that question even though he knew that I had not grown up in a Jewish home and would likely know what real crab tasted like as well. He was very careful to observe the mitzvah to not remind a convert that they were not always Jewish.
