"Made this last night for both french onion soup lovers and non-lovers alike. Everyone loved it. Browned the onions in two different pans and it worked fine. I just waited until they got mushy, I think they took longer to cook than the receipe said. I took a suggestion from another reviewer and poured the Guiness into a glass first. The soup was bitter until I added the beef stock and let it simmer. I used red wine vinegar instead of sherry, since I didn't see the point in buying something I didn't have and probably would not use again. We finished the pot and everyone wanted more, plus the receipe. I'll definately make it again."
