Yeast Rolls

I found this recipe online. Supposedly it's the recipe for "back in the day" school yeast rolls.

1 pkg dry yeast
1/4 cup warm water
1 cup milk scalded
1/4 cup sugar
1/4 cup shortening
1 teaspoon salt
3 1/2 cups sifted all purpose flour
1 egg

Dissolve dry yeast in (110 degree) warm water. Let stand for 4-5 minutes. Add the shortening, sugar, salt, flour, to the scalded milk, and beat/mix until milk cools to warm. Then, I add the egg to keep it from cooking in the hot liquid. Mix for 1 minute on low speed. Add dissolved yeast and mix for 2 minutes on low speed. Knead dough on medium speed for 8 minutes, or until dough is smooth and elastic. Place dough in warm area (about 90 degrees F) for 45-60 minutes. Punch down dough to remove air bubbles. Form rolls from dough by pinching off 2 oz. pieces and shaping into balls. Place rolls in rows on sheet pans lightly coated with cooking spray. Place in a warm area (about 90 degrees F) until double in size, 30-50 minutes. Bake until lightly browned in oven at 400 degrees F for 18-20 min. They are great.
