CELERY ROOT SALAD WITH ARUGULA AND PECANS

Steps:

• To make the mustard vinaigrette, use a mortar and pestle or the flat side of a knife to smash the garlic and a tiny pinch of salt to make a paste. Whisk the paste in a small bowl with the mustard, vinegar and remaining salt. Whisking constantly, slowly drizzle in the oil until fully incorporated. Season with pepper.
• To make the salad, fit a food processor with a large grating blade; grate the celery root. (You can also use a box grater, though beware your knuckles.) Transfer to a large bowl and add the arugula and pecans. Pour the vinaigrette over the salad and toss well. Season with more salt, vinegar and olive oil if needed before serving.
