One thing that I’ve learned as an adult is NOT to say a dish MUST be prepared a certain way. You get that a lot when talking about soul food, or any other ethnic cuisines like Jamaican or Nigerian. I’ve found that foods can be prepared differently from what you were brought up on and still be just as good. Plus food is inconsistent from household to household. Folks palettes are informed by how they grew up. If their parents were bad cooks, their palettes will have gotten used to bad cooking and may not be able to discern actual good food even if it smacked them in the face.
Agree with this, to an extent. In some cases, the strict prep/cooking instruction is valid. We put up interviews with the late Lena Chase at her restaurant in New Orleans when she was alive. The sweetest woman ever.............until somebody suggested a different way of making or eating gumbo. We had a running joke on who she would scream on next. Renaissance man Howard Conyers, Obama, Roland Martin all got screamed on. hehehehr
Rest In Peace to her.
But in general and for later generations, I don't think those kind of strict rules apply much. Because of migration, immigration, etc many people have parents from different regions, cultures, or countries. Two grandmothers from different backgrounds opens up your mind and palette to different foods. And the same foods being prepared differently. Merges, mixtures, and blending will naturally occur,
Also, people travel more frequently and widely than in past eras. This exposes them to different ways and ideas to prepare the same foods. You brought up an interesting comment in the thread about John Young, the King of Buffalo Wings. Like you pointed out, Mumbo/Mambo Sauce made it's way to DC via people who had visited the restaurant/store in Chicago where it was made/popularized.

In Buffalo, Mr. Young's daughter said that he tinkered/experimented with his sauce early on. And that after traveling internationally that he picked up some spices/fruits to add to what became his signature version of Mambo Sauce.
