I've discovered some really great cooking shows on Amazon from the 80s and 90s through today
The nice thing is that it seems ingredients have only gotten easier to find for the recipes from those years.
My favorite, so far, has been "A Taste of History" which is more recent, but it's a German Chef who immigrated to America, cooking in the style that the colonists from the 1700s would have used, cooking over an open hearth.
The fun bits of history that are included have been enjoyable as well.
The Julia Childs shows and the "Great Chefs" series are quite good too. There's a lot of options on Amazon prime for those who are interested.
