Craggy, tangy sourdough discard English muffins with real nooks and crannies. A wet dough, bread flour, and an overnight rest do the work, and they cook up on a skillet and freeze perfectly.
The single most important step is not adding flour to the sticky dough. Chill it and handle it gently instead.
Cut straight down and do not twist the cutter, which seals the edges and closes the crumb.
Judge doneness by internal temperature (195 to 200°F), not by color.
All-purpose flour works but gives a tighter crumb. Bread flour gives the most open, craggy interior.
These freeze very well. Split before freezing and toast straight from frozen.
