Fried foods date back to ancient cultures in Europe, Asia, and even North America. In medieval times, fried chicken was already being eaten in western Europe. Scottish immigrants to the United States are often credited with being the ones to introduce fried chicken to the country where as most other European immigrants to the country ate baked chicken.
I am a dyed in the wool Scot, and I love Scottish cuisine. But I have never had fried chicken in Scotland in the 30+ years I’ve been visiting there. My grandmother, whose own parents were Scots, made delicious fried chicken, but she never so much as suggested that it was a Scottish recipe.
