I've been enjoying celeriac since I accidentally planted it instead of celery. It's a go to side at Thanksgiving. I've experimented with all sorts of cooking methods from roasting to boiling to frying. Poached Pear is an excellent addition. I've spiced it different ways with cardamon (my fave), horseradish, cayenne and other stuff. Always with butter and cream, usually wizzed in a food processor, none of that passing it through a sieve stuff, there's enough to clean up already. Super flexible, always a hit...
