there fun and easy to use. I have a 1/2 cream can. put corn on cob, cabbage, onions potatos and kauasba sausage and 6 beers. layer all then put the 6 beers in for liquid. Can use anything water, wine, coffee. put alum foil on top and poke holes in foil. Place on burner once stream starts coming out about 1/2 hour then done. Place in cooler and it will stay hot for about 4 hours.
