"What warms you up more than buffalo-style anything? Here's my buffalo burger, made with beef instead of chicken—and plenty of blue cheese!" —Rachael Ray
In a medium bowl, mix the celery root and lemon juice; season with salt. Mix in the sour cream, carrot, herbs, and Dijon; season the celery root slaw with pepper.
Heat a large cast-iron or other heavy skillet over medium to medium–high.
In a medium bowl, season the beef with salt and pepper. Mix in the granulated garlic and onion, hot sauce, and Worcestershire. Form into 6 patties (thinner in centers for even cooking).
Melt 1 tbsp. butter in the skillet. Add 3 patties and cook, turning occasionally, for 8 minutes. Repeat with the remaining 1 tbsp. butter and 3 patties.
Top the bun bottoms with the slaw, patties, blue cheese, pickles, and the bun tops.
Note: Any leftover celery root slaw is great on deli-meat sandwiches.
