These are from a mimeographed, hand bound cookbook given to me by Lioness Joan Nielsen of Marshall, Saskatchewan, about 20 years ago. Marshall isn't quite Alberta, but it's just a few miles east of the border on Highway 16. The book is full of prairie standbys so if you need more, let me know. The can sizes aren't given. I would guess 14 ounces (400mL) but you may have to experiment. Hamburger Casserole Lioness Marilyn Eric, Marshall
