For those unfamiliar, you may be wondering, what exactly is a Friday Fish Fry? I had to do some research about its beginnings, and here’s what I discovered. Many European immigrants came to areas like Milwaukee and Chicago from Germany, Ireland and Norway. From there, they had to adapt their cooking style for the fish easily accessible in Lake Michigan. Many of these immigrants were Catholic and could not eat meat on Fridays during Lent, so the weekly fish fry became tradition.
