Instructions
In the bowl of a stand mixer, combine the warm milk, warm water, sourdough discard, honey, and instant yeast. Whisk until mostly combined.
120 g whole milk, 120 g warm water, 150 g sourdough discard, 14 g honey, 4 g instant yeast
Add the flour and salt. Using the dough hook, mix on low speed until a shaggy dough forms, about 2 minutes.
360 g all-purpose flour, 7 g fine sea salt
Add the softened butter and continue kneading on medium-low speed for 6-8 minutes, until the dough is smooth, elastic, and very soft. The dough should be noticeably tacky and softer than a typical sandwich bread dough; avoid adding additional flour unless it's truly soupy and unable to hold together.
28 g unsalted butter
Transfer the dough to a lightly greased bowl and cover. Let rise in a warm place for 60-90 minutes, or until noticeably puffy and approximately doubled in size.
Line a sheet pan with parchment paper and generously sprinkle it with cornmeal or semolina. Turn the dough onto a lightly floured work surface and gently press it into a thick rectangle about ½-¾ inch thick, without aggressively deflating it.
Cornmeal or semolina flour
Shape the muffins one of two ways. Either cut out rounds with a 3-inch cutter, using a bench knife to lift them cleanly off the counter (this dough sticks even when floured), and gently gather and reroll the scraps once to cut the remaining muffins; or, for an easier alternative with similar results, divide the dough into 10 pieces and roll each into a ball by hand. Transfer the shaped muffins to the prepared pan and press gently into the cornmeal or semolina to coat. You should get about 10 total.
Sprinkle the tops with additional cornmeal or semolina. Cover loosely and let rise for 30-45 minutes, until the muffins look noticeably puffy.
Preheat a large cast-iron skillet, griddle, or heavy-bottomed skillet over low to medium-low heat until thoroughly heated but not smoking. Carefully transfer several English muffins to the dry skillet, leaving room between them.
Cook for approximately 6-8 minutes on the first side, until deeply golden brown, then flip and cook for another 6-8 minutes. Keep the heat relatively low so the outsides don't brown before the centers finish cooking.
The muffins are done when both sides are golden brown and the centers reach approximately 200°F on an instant-read thermometer. If they're browning too quickly, reduce the heat, or transfer browned muffins to a 350°F oven for 5-8 minutes to finish cooking through.
Transfer to a wire rack and cool completely before splitting.
Notes
Don't slice English muffins with a knife. Insert the tines of a fork around the entire outside edge of the muffin, then gently pull the two halves apart to preserve the craggy pockets inside.
For even more sourdough flavor, prepare and knead the dough as directed, then cover and refrigerate it overnight for 8-12 hours. The next morning, let the dough sit at room temperature for about 20-30 minutes, then shape, proof, and cook as directed.
