Soften yeast with 1/4 cup of warm water and wait at least five minutes.
In mixer combine sugar, shortening, salt, and scalded milk; cool to lukewarm.
Add softened yeast, egg, and 2 cups of the flour; beat well. Gradually add remaining flour to make a soft dough.
Cover and let rise in a warm place for 90 minutes.
Punch down dough and pinch off pieces of dough to roll by hand into small balls---each ball a little smaller than a walnut or a large marble. Generously grease muffin pan. You will place three balls together in each muffin holder.
