Creamy Celery Root Salad With Red Peppers and Mustard

Covered in grime, knobby as a goblin, and incredibly fibrous and tough, celery root deserves a place in the "Now who'd have thought to eat that first?" category of foods. But perhaps once was sliced into, and its gruff shade gave way to a moon-like pallor, and a deliciously fresh scent was released; that may have been enough to compel one. And since then, many have done much to showcase the unlikely edible's charms. Like slicing the root finely, and dressing it fresh.
