Note
1. Set a large pot of salted water on high heat and bring to a boil.
2. Squeeze out as much water as possible using a muslin cloth or nut milk bag (a paper towel or clean cooking towel will work, too).
3. Fire up your oven, aiming for 750°F to 850°F (400°C to 450°C) on the baking stone inside.
4. Melt the butter, mix in the garlic, and set aside.
5. Transfer the cool, dry grated potatoes to a large bowl.
6. Use a rolling pin to flatten out the dough until it's ½-inch (1-centimeter) thick.
7. Brush the flatbreads with melted garlic butter and top with grated cheddar to lightly coat.
8. Launch the flatbreads into the oven and cook for 2 minutes, rotating every 45 seconds or so, until the dough is browned and the cheese is nicely melted.
9. Retrieve the flatbreads and finish with a drizzle of extra-virgin olive oil and a scattering of grated cheddar.
10. Serve warm and enjoy.
