Not quite! Next week is semifinals, then finals the next week.
I don't think I've ever seen salsify (I'm in the US), but celery root is around and I'll sometimes buy it (to roast or mash (try with cream cheese & everything bagel seasoning! I think I got that from Blue Apron), although you can also do a celery root salad). I didn't encounter it until I was at least 30, though, and probably only started using it semi-regularly in the last 10 years. Still, it feels like it's always been there, and I just didn't know how to use it and avoided it because I don't much like celery. Anyone w
