In a small bowl, combine the yeast and warm water with 1 TBSP of sugar. Stir gently and let sit for 5 minutes until foamy.
In a the bowl of the stand mixer, add the egg, milk, melted butter, salt, the other 1 TBSP sugar, and 2 cups of flour. Add the yeast mixture and mix until smooth.
Add the remaining flour and using a dough hook on a stand mixer, mix for 5 minutes. This can be done by hand on a floured surface. Knead the dough for 10 minutes. The desired dough should be manageable, though sticky to the touch. Don't over-flour the dough.
Place the dough in an oiled bowl and cover to proof. Place in a warm area for one hour or until it is doubled in size. If you have a colder house, you can use your oven, just set it to 38˚C/100˚F. Once at the temperature turn off the oven and place the covered dough inside.
Once proofed, punch the dough and pour it out onto a floured surface. Divide the dough into 16 even pieces. If you have a cutter, roll out the dough until it is just under 1 inch thick and use the cutter to cut out 16 muffins.
Line baking trays with baking paper and sprinkle with the polenta/cornmeal.
Sprinkle flour on your hands and roll each piece into a ball and place on prepared tray.
Gently press each ball with the palm of your hand, forming 'pucks' that resemble English muffins. Do not press down too hard as they will deflate.
Sprinkle the tops with the polenta/cornmeal as well.
Cover with a clean cloth and place in a warm area and allow to rise for 1 hour.
Heat a cast iron skillet on medium-high heat, then place as many English muffins in your pan as can fit without crowding.
Cook on one side until golden brown, about 5 minutes before flipping and repeating with the other side. This may take longer if not using cast iron.
