was called a "jelly roll" back in my day.... bubble with oil together. If you warm, and work your bubble.. you can flatten it out in the shape of a small, a thick tortilla, then you spread oil on the top.. like frosting a cake.....then you roll it up like a tight burrito...then cut your burrito in thin slices (3/8 to 1/2 inch)... they look like little cinnamon rolls.... Now throw one of those "jelly rolls"on the screen.....
Heck just remembering bout em ...makes me want to make some up... mite just do that and make a pictorial of it...
