A great recipe, but ruined by using Guinness Extra Stout; this version of the beer resulted in a very bitter-tasting stew.
I had made the stew the night before I needed it, so I let it sit overnight, and tried to alleviate the bitterness by using several of the tips outlined here: http://chowhound.chow.com/topics/483649
Unfortunately, nothing could really get rid of the bitter aftertaste, especially in the vegetable, which seemed to soak it in.
Lesson learned -- next time, I'll use straight Guinness, or a slightly more mellow stout.
My husband is a meat and potatoes sort of guy, and his favorite beer is Guinness. I couldn't wait to make this recipe for him. It turned out awesome! The Guinness gave the stew such a wonderful flavor.
