Anyway...you know you're a homebrewer when you add beer to your BBQ sauce. 
Things I've added beer to this year - chili (pale ale, brown ale, or anything), punkin pie (punkin ale), baked cod (wit), tacos (any wheat), brats (obvious), and I have homebrew stout beef stew cooking right now. I think I'll have to add some to my turkey brine this year.
I tried adding beer to salad dressing too, but that didn't work out.
There's a great recipe for blue cheese dressing in Schermerhorn's Great American Beer Cookbook that uses mead (or cider). It may be the best salad dressing I have ever had.
