Cornish Pasties are made differently in every region. My father and grandfathers were Cornish lead miners in SW Wisconsin. Ours were made with just onions, potatoes and sirloin steak. The steak must have some fatty part or lines in it. Also add small pieces of butter, salt and pepper. My mother drifted away from the pasty form and made them in pies. Large family and saved time. I do know when her father worked in the mines in Galena and Mineral Point, he carried them to work. Hope this helps. I plan on making them today for the weekend. They freeze beautifully.
