How to make celery root dish without parmesan?
I find celeriac loves coriander -seed and especially root. White pepper, horseradish or perhaps mustard oil or powder can be added by a smidge for a hint of warmth.

This is still a mild side-dish, ya for something else flavorful on the plate?
I love serving pumpkin at the same meal 'cause they bring out the best in each other... IMHO.
