I've never cooked with them and have only eaten them twice, both times at one of our favorite restaurants up in Sonoma wine country. The second time I saw them on the menu it had been a year since the first time. The chef has a large garden out behind the restaurant (which is currently her dining room since there's no inside dining) so it was probably that we were there both times when they happened to be ripe. When I saw them the second time I was like OMG! OMG! Sunchokes again! One of my super favorite food things but I've never seen them in a store. The dish I had (the same dish both times) was some sort of flaky white fish served on a bed of sunchokes and butter beans. Unfortunately I have no idea how specifically they were cooked.
