Dept. of Agriculture in Missouri has a fantastic Extension center with monthly newsletters about canning, gardening, etc. I collected several books on canning from them. The recipe here is posted at request.
Found this delicious recipe in an insert from ol' Elsie Borden. It was stuck inside a cookbook, the recipes dated to 1994! Love the sour cream/taco seasoning combination tucked in between the beans and the avocado spread!
