Whole-Wheat English Muffins

Ingredients
    2 teaspoons/7 grams active dry yeast (1 packet)
    4 tablespoons/60 grams unsalted butter
    ½ cup/120 milliliters plain yogurt
    ½ cup/120 milliliters warm whole milk
    ½ tablespoon/7 milliliters honey
    1 teaspoon/5 grams fine sea salt
    1 cup/125 grams whole-wheat flour
    1 cup/125 grams all-purpose flour
    ½ teaspoon/4 grams baking soda
    Cornmeal, preferably coarse, as needed
Preparation
    In a small bowl combine yeast and 1/3 cup warm water (80 milliliters) and let rest until yeast has dissolved, about 5 minutes.
    Melt 2 tablespoons butter and put it in a large bowl. Whisk in yogurt, milk, honey, salt and the yeast mixture.
    Add flours and baking soda to bowl and beat thoroughly with a spoon or rubber spatula until well combined. Cover bowl and let rest in a warm spot for 1 to 1 1/2 hours, or until dough has doubled.
    Heat oven 350 degrees. Lightly dust a small baking sheet with cornmeal.
    Place a large skillet over medium heat and melt 1 tablespoon butter. Using a large ice cream scoop or 1/2 cup measuring cup, drop batter into skillet to form round muffins about 4 inches in diameter, mounding the batter in the center. (You may need to coax the dough a little with your fingers, so be careful of the hot pan, and don’t worry if they’re not perfectly circular.) Repeat until you have 3 muffins, leaving the rest of the batter for a second batch. Reduce heat to low. Cover skillet with lid or baking sheet and cook 3 to 5 minutes, until bottoms are golden brown. (Be careful not to let them burn.)
    Uncover skillet and flip muffins using a spatula. Cover again and cook 2 to 4 minutes or until the other sides are golden brown. Place muffins on prepared baking sheet. Repeat using remaining batter and another tablespoon of butter.
    Bake muffins for 6 to 9 minutes, or until puffed and cooked through. Split the muffins with a fork and toast before eating.
