my parents full German on father, German/Scottish on my mother side.
it was always call blind fish in our house and it would be served at suppertime on rare occasions , I liked it cause it was a sweet meal with the maple syrup.
As being the youngest I spent the most time living with my Grandparents before going to school, I dont remember ever eating this there.

Bread ( the heal was the best part for me.) dipped in scrambled egg no milk added. 2 second dip & flip and out into pan.

none of my friends at school ever heard it call that so I always assumed it was a Scottish descent term rather than a German phrase, but I only had 1 Grandfather that served in WWI he got his citizenship by serving for the US Army from Scotland. He never made it to the front line but was stationed in France for the last 6 months of the war..   So did he bring the term with him and where did he get it from ..... hows that for guessing where the term originated
