Dissolve yeast and sugar in warm water. Heat milk, butter, and salt in a saucepan until butter is melted. Cool to luke-warm and add to yeast. Add 4 cups flour, beat batter well. Cover and let rise in a warm place for 1 hour.
Stir down, add remaining 2 cups flour to make a stiff dough. Knead on a floured board until smooth and elastic. Turn in a lightly oiled bowl. Cover and let rise until doubled -- about 1 hour in a warm place, overnight in the refrigerator.
Punch down, pat out ½ inch thick, cut into 3 inch rounds. Dust both sides with cornmeal; let rise until double. On a lightly greased griddle over low heat, carefully brown on both sides. To serve, split & toast.
Kirk likes English muffins. This makes about a dozen.
