preheat oven to 425. Grease 8 muffin cups.

In a large bowl, mix the shortening, sugar, and hot water. Allow to cool until lukewarm, and mix in the yeast until dissolved. Mix in the egg, salt, and flour. Allow the dough to rise until doubled in size.

Divide the dough into the prepared muffin cups, and allow to rise again until doubled in size.

Bake for 10 minutes in a preheated oven, or until a knife inserted in the center of a muffin comes out clean.
