This delicious winter Celery Root & Apple Slaw salad uses a quick and easy version of the classic French remoulade sauce. Remoulade sauce is usually made with egg yolks. To keep things simple, we’ve... used store bought mayonnaise to add the richness of eggs without any hassles. It’s seriously delicious. The sauce blends wonderfully with the earthiness of the celery root and pops the sweetness of the apples.
