I'll have to admit that I did a double-take when I saw this post. It sounds like a great idea, though - parsnips are pretty uncommon food in this day and age but prepared well they can be delicious.
There's one thing to always remember with parsnips, though. They always taste much better after a frost. I grow them up here, and they're one of the few veggies you can harvest even when there's snow on the ground (which is good because they grow very slowly). I'd swear that they get way sweeter after they've been lightly frozen and thawed, because the starch in them converts to sugar.
In fact, that's the only way I like to eat them. They've got a strange taste when they're picked fresh and not everyone finds them very pleasant. Your results will definitely vary, but if I buy new parsnips at this time of year I like to stick them in the freezer for 30 minutes or so before they go into the fridge for storage.
Unlike propane, you'll never wake up scorched and naked in another county because you mishandled a bag of briquettes.
