"I found this recipe last year on the internet and i'm obsessed with it :) I would like to try this with stew meat bc as much as i love short ribs, they are large and can't fit many in a crock pot and there isn't a ton of meat on them either."
Place onions in a 5-qt. slow cooker; add ribs and bay leaf. Combine the beer, brown sugar, mustard, tomato paste, thyme, bouillon, salt and pepper. Pour over meat. Cover and cook on low for 8-10 hours or until meat is tender.
Remove meat and vegetables to a serving platter; keep warm. Discard bay leaf. Skim fat from cooking juices; transfer juices to a small saucepan. Bring liquid to a boil. Combine flour and water until smooth. Gradually stir into the pan. Bring to a boil; cook and stir for 2 minutes or until thickened.
