Potato (Peel) Focaccia

• 1 cup (4 to 5 ounces) lightly packed potato peels (see headnote for more)
• 4 cups (17 ounces) all-purpose flour
• 1 tablespoon kosher salt
• 2 teaspoons instant yeast
• 6 tablespoons olive oil, divided
• 2 teaspoons butter, softened, for greasing
• Flaky salt for sprinkling
• Loaded Baked Potato variation
• 4 green onions, thinly sliced
• 3 tablespoons (3/4 ounce) bacon bits (see headnote for more)
• 1/2 cup (3 ounces) packed grated cheddar cheese

1. Place the potato peels in a small saucepan with 1 1/2 cups water. Bring to a boil over medium-high heat, then reduce heat to maintain a simmer over medium heat. Cover and cook until the peels are very tender, 20 to 30 minutes. Allow to cool slightly.
2. Meanwhile, in a large bowl, whisk together the flour, salt, and yeast. (If making the Loaded Baked Potato version, add the sliced green onions, shredded cheese, and bacon bits, and stir to mix.) Set aside.
3. Transfer the peels and remaining cooking water to 2-cup measuring cup (or larger), puree using an immersion blender, and then add more water to reach the 2-cup mark (if you do this before blending you risk making a mess). Alternatively, the peels and cooking water can be transferred to a blender instead. This potato peel water mixture needs to be in the 95u0b0 to 115u0b0 F range for happy yeast, so I blend when the mixture is still warm, then add cold water, check the temperature, and if it's still too warm, wait for it too cool off. If you don't have a thermometer, fear not, just check the temperature by putting a few drops on the inside of your wrist, it should feel warm, but not hot.
4. Pour the potato peel water mixture into the dry ingredients, and, using a rubber spatula, mix until the liquid is absorbed and the ingredients form a sticky cohesive mass of dough. Pour 2 tablespoons of the olive oil in the bottom of a large container with a lid (or use the same bowl that you used to mix!), transfer the dough to the container, turn to coat in oil, then cover and refrigerate for 24 hours. (Okay, or 18 hours if that works better for your schedule. Okay, okay, *at least* 12 hours, but that's the minimum, and really, 24 hours is best. Patience is a virtue and all that.)
5. Grease two 8- or 9-inch pie plates (or something similar) with 1 teaspoon butter each, then pour a tablespoon of oil into the center of each pan. Deflate the dough and separate it into two equal pieces (Alexandra Stafford does this with two forks and it works really well). Place one piece into each of the prepared pans. Roll the dough balls in the oil to coat them all over, and let the dough balls rest for 2 to 4 hours (depending on the temperature of your kitchen), until they have poofed up and filled the pans.
6. Once the dough balls look like they've had enough rise time (or close to it), heat your oven to 425u0b0 F. Once your oven is at temp, drizzle the remaining olive oil on them (1 tablespoon on each), stipple the dough with your fingertips to create deep dimples, sprinkle with flaky salt, and then put them directly into the oven. Bake for 25 minutes, or until golden brown all over.
7. Remove from pans, transfer to a cooling rack, and wait patiently. (Or rip into it while it's warm, I won't tell.)
