Also called celeriac, celery root is a favorite of ours. It’s from the base of the plant that celery shoots up out of the ground from. We’ve cleaned them up to the point that all they need is a quick easy peel and they’re good to chop. They have a deeply celery flavor but a much heartier texture. It does great chopped and roasted, in soups or stews, or anywhere that you would otherwise use celery.
