I was wondering about a detail of a recipe I recently read in a magazine.
The recipe is for Gnocchi, so basically it's about making a potato mash dough.
Instead of just boiling the potatoes, the recipe was roughly like:
Put the whole, unpeeled potatoes into a large casserole, cover them
wholly with ample stone salt, and slowly bake them for 2 hours. (…
then peel cooked potatoes and put them through a ricer … …)
What gives? I'd just put them into a steamer and cook them, what's the point of putting them into the oven for 2 hrs covered with salt?
(Note: It was a recipe from a posh restaurant, so it may well be more complicated than necessary 🙂

The only answer that makes any sense (other than the "just for show" hypothesis) is that baking in salt does create a fluffier potato. That assertion is backed up by Cook's Illustrated and the Idaho Potato Commission [citation]. So, for the lightest possible gnocchi, start with the fluffiest possible potato.
I've got to say though, roasting potatoes in salt for gnocchi would be too fussy even for me.
EDIT: One other possibility just occurred to me, and the more I think of it, the more I think it's the key. Maybe the restaurant always bakes potatoes that way and it's just as easy to add extra for the gnocchi or to use leftovers. So, they wrote the recipe the way they actually do it.
