Brown beef in a 6 qt. kettle, cook until brown. Add onions and cook till soft. Stir in tomatoes (break up) and their liquid, tomato puree, beans, Worcestershire, bitters, carrots, beer, garlic, bouillon cube, red pepper flakes, bay leaves, chili powder, coriander, cumin, thyme, oregano and basil. Bring to a boil, turn heat down to simmer, uncovered, stirring occasionally, until thick (about 2 hrs.). Skim fat and remove bay leaves. Pour into bowls. Top with shredded cheddar cheese, sour cream, sliced green onions (including tops). NOTE: I like the coarsely ground meat for this recipe. Most markets will do this for you, but sometimes you have to give them advance notice. Most markets run the meat through the grinder twice daily, just ask them to give you the once through. Use cuisinart for chopping garlic and carrots.. Secret is bitters and beer, don't leave them out.
