This classic French side dish features a creamy dressing of mayonnaise, mustard, anchovies, cornichons, and herbs.
In a food processor, pulse the cornichons, parsley, tarragon, and anchovy (if using) until coarsely chopped.
Add the mayonnaise, sour cream, lemon juice, mustard, and zest and process until well combined. Scrape the dressing into a large bowl.
Fit the processor with a medium grating disk. Peel the celery root with a knife (rather than a vegetable peeler) and cut it into chunks small enough to fit into the processor’s feed tube. Grate the celery root in the processor.
Transfer the celery root to the bowl of dressing and fold gently to combine. Season to taste with salt and pepper and serve.
