Celeric is a root vegetable with a celery taste. Purees and mashes are a popular way to eat this in the winter. It can be eaten raw, but oxidizes quickly so have a bowl of lemon water as you are cutting. I see a lot of recipes that use fennel with it in soups and gratins.
Dena provides a simple salad recipe below.
