For the sloppy joes: Heat the butter in a large skillet over medium-high heat. When the butter foams, add the turkey. Brown and crumble. Season with celery salt and pepper. Add the thyme, chopped celery, chopped carrots and onions. Cook, partially covered, to soften, 12 to 15 minutes. Then deglaze the pan with the beer. Add the hot sauce, vinegar, Worcestershire and tomato sauce. Then simmer to thicken. Cool and store for a make-ahead meal. Reheat over medium heat to bubbly hot.
For the dressing: In a bowl, combine the blue cheese, sour cream, herbs, lemon juice, garlic and some salt and pepper. Whisk in as little or as much of the buttermilk to the dressing for the consistency you like.
Serve the sloppy buffalo meat on rolls topped with the pickles, onions and a dollop of dressing. Serve the additional dressing for dipping the carrot and celery sticks alongside.
