one thing you have to remember is that 90 percent of American recipes are made by people pushing an agenda …i mean how many people have found out grandmas secret pie recipe came from a free cookbook given to her my the “apple Growers Washington” whose job was coming up with ways to sell more apples in 1921 but over the years just made from either memory or a unsourced card so the source was forgotten
Or mom’s fudge recipe was the recipe that was on the back of the marshmallow cream jar?
If you want to see how American cooking /was is manipulated by companies and groups look up the "baking powder war "
