The parboil with salt & baking soda roughens up the surface of the potato at a near-microscopic level. Then you quickly drain the pot and dry the potatoes in the emptied cooking pan, stirring constantly- it rakes a minute or two.
After the parboil & dry, the potatoes will look almost...fuzzy. That’s beca all those mini-abrasions are juuuuust too small to see clearly.
Then you bake them according to your usual method.
And those abraded surfaces will crisp up like magic!
