I have never tried it either, so very interested to see what pops up here. Always love a new food adventure. From my investigative works, it appears that it is very similar to the parsnip. I found it roasted, used in slaws and a puree accompaniment for fish.
Here's the roasted version i found:
For the salsify:
Peel the salsify and slice into two inch pieces on the bias. Season with salt and olive oil. In a saute pan, add half the duck fat; pan fry the salsify, add the chicken stock and butter. Cook quickly on the stove. Reduce the stock completely and remove the salsify. Heat a clean frying pan until it's very warm, pour the remaining duck fat, and roast the salsify until it has a golden color. Season with pepper and "fleur de sel." Reserve on the side until you are ready to plate the dish.
What the heck is "fleur de sel", you ask...i have no idea!
