The salt potato is a wonder to behold. Those who think that they have experienced the true essence of earthy starchiness that is the potato but have not tried this method are in for a surprise. The secret is to not be afraid of the salt. A true salt potato is boiled in water salted in a ratio of 1 pound salt for every 4 pounds of potatoes. Yes, that is a lot of salt. It’s so much salt that it crystallizes on the skins of the cooked potatoes, making them look like something dug up on a paleontological excavation. But, boy, do they taste great.
In this recipe the salt content is reduced and the potatoes are then further subjected to the withering heat and smoke of an aromatic fire. The result? An addictive melding of salty, crunchy, fluffy, flaky goodness.
- Place the potatoes in a pan just large enough to hold them and provide a little headroom. Cover them with cold water and add the salt. Cook over medium heat until the potatoes are fork tender, 15 to 20 minutes. Drain the potatoes and let them cool slightly.
- Set the potatoes in the embers of a dying fire and cover the grill. Cook until the skins are blistered and the potatoes are heated through, about 20 minutes. Remove them from the coals and brush off any ash. Cut them in half and arrange them on a platter.
- Combine the scallions and sour cream with a pinch of salt in a food processor. Purée until the mixture is smooth. Check the seasoning and adjust if necessary, but consider the salt content of the potatoes.
- Serve the potatoes either warm or at room temperature with the sour cream sauce.
