Line a baking sheet or flat surface with parchment paper and sprinkle with cornmeal.
After 8-12 hours, flour a clean surface and transfer your dough onto the floured surface. (You should notice your dough has increased in size significantly over this period)
Using your hands or light pressure from a rolling pin, flatten your dough to approximately 3/4" to 1" thick. (You can lightly flour the top of your dough and the rolling pin to prevent sticking. Adding a light spray of water to your hands will also help prevent the dough from sticking to your fingers).
Use a biscuit cutter or round object approximately 3-5" in diameter to cut your muffins. Place each muffin onto cornmeal surface then sprinkle top with remaining cornmeal.
(If scrap dough remains, you can reform into dough ball and press out onto flat surface again to utilize. Be sure not to over knead the dough.)
Once all muffins are made- cover with clean damp towel and allow to rest and rise for 1 hour.
Warm a pan or cast iron skillet over low heat and oil with avocado oil or coconut oil. To preheated skillet, add 4 of your muffins and cover with a lid.
Allow muffins to cook on each side for 6-8 minutes (covered) or until slightly browned on the surface. (Ensure your heat remains on low to avoid browning too quickly)
Remove muffins and repeat until all are cooked! English muffins are fully cooked when internal temperature reads 200 °F
Enjoy!
