Preheat the oven to 425˚. In a medium bowl, place the butter and beat with a wooden spoon until creamy, but not melted. Add the shallot, the tarragon and a sprinkle of sea salt. Mix well. Slice the potatoes into very thin wedges, leaving them joined at the bottom. You may rest the potato on two wooden chopsticks as a guide for when to stop slicing. Fan out the slices and place the potatoes on a parchment-lined baking dish. Using about 2 tablespoons of the tarragon butter, brush the potatoes generously. Place in the oven and roast for approximately 60-70 minutes (depending on the size), brushing the potatoes every 15 minutes with the tarragon butter, using a total of approximately 4 tablespoons. The potatoes should be crispy and cooked through. Serve fresh out of the oven, sprinkled with sea salt and fresh tarragon. Bon appétit!
Use the rest of the tarragon butter and serve these potatoes with sautéed corn and peas. To do so, in a medium skillet, mix some kernels from two ears of corn, a bag of thawed green peas (or fresh, even better), the rest of the tarragon butter, and one extra small shallot, minced. Cook over medium heat until the butter is melted and the mixture is heated through. Season to taste with sea salt and pepper, and serve alongside the potato. Delectable!
