I got this recipe from http://www.thefreshloaf.com/node/3241/sourdough-english-muffins
Sourdough English Muffins
Makes about 12
1/2 C starter (mine is a 100% hydration white starter)
1 C milk
2-3/4 C AP flour
1 TBSP sugar
3/4 tsp salt
1 tsp baking soda
Semolina or cornmeal, for dusting
Combine starter, 2 C of flour and milk in a large bowl. Stir to combine, cover with plastic wrap, and leave out for 8 hours or overnight.
After the overnight rest, add remaining flour (I didn’t add any), sugar, salt and baking soda and mix well. Turn onto a lightly floured surface and knead for 4-5 minutes. Roll out to 3/4″ and cut with a biscuit cutter into rounds. You can reroll the scraps, but you may need to let the dough rest before cutting more muffins from them. Place muffins on a piece of parchment dusted with semolina and let rest for 45 minutes.
Spray griddle or skillet lightly with spray oil. Heat to medium and cook muffins for about 6-8 minutes on each side, or until browned on the top and bottom and cooked through. These have great griddle spring and rise quite a bit during the “baking”.
Split with a fork and enjoy with your favorite topping! I don’t even toast them if I want to eat them right off the griddle–they don’t have that raw taste that storebought english muffins have.
