Scald the milk, and add the butter. When it grows luke warm, add the yeast, the flour and salt, and beat all well for about ten minutes. Then set the bowl in a warm place, cover with a cloth, and let the mixture rise for about two hours. When very light, beat well again, and add two eggs well beaten. Turn into muffin rings or gem pans, and let them rise a half hour longer. At the end of that time place them in the oven and bake for about twenty minutes. If yeast powder is used, beat into the batter, and proceed to bake immediately. The Muffins may be baked in muffin rings, or on a griddle.
