Cooking with beer is definitely a "get what you pay for" adventure.
If you use Bud, Coors, Miller, Milwaukee's Best or any of the other
"mainstream" beers, you will get some beery bitter flavors... yuck!
Instead, try an IPA or Pale Ale for a nice fruity flavor....
A bold Black and Tan, Stout or other dark beer is a nice addition to bold foods....
I have a plan for a Chocolate Stout and some chili.....
Next time you are in the beer section, look for SARANAC brand beer. They provide
a nice and accurate description of their beers' flavor notes on the neck label.
Read a few of them and you might get some ideas for beer cooking that surprise
