Here's a great recipe for serving a lot of people who eat at different times. Its easy and will be a big hit. Depending on the amount you need to cook choose an appropriate size aluminum roaster pan. Pour beer into it. You want enough beer so the brats can take a bath. Add onions and butter and let simmer. Put the brats in and let them cook away. After about an hour take them out and grill them until nicely browned. Always use good buns for brats. Save the cheaper buns for hot dogs. Enjoy.
