Activate the Yeast: Begin by preheating your oven to 400°F (204°C). In a large mixing bowl, combine the dry active yeast and warm water. Set a timer for 10 minutes and let the mixture sit until it becomes frothy. This step ensures that the yeast is alive and ready to help your dough rise to perfection.

Mix the Dough: Once the yeast is frothy, add the sugar, salt, egg, and vegetable shortening to the bowl. Mix these ingredients together until they're well incorporated.

Let the Dough Rise: Cover the bowl with a clean kitchen towel and let the dough rise for 30 minutes in a warm, draft-free place. The dough should roughly double in size.

Shape the Rolls: Once the dough has risen, punch it down to release any air bubbles and turn it out onto a floured surface. Divide the dough into 12 equal portions and roll each piece into a smooth balls. Place the dough balls into a greased baking dish, leaving a little space between each roll to allow for expansion. Cover again and let them rise for an additional 30 minutes.

Prepare for Baking: After the second rise, brush the tops of the rolls with the egg white. This step will help create a beautiful golden brown crust.

Bake to Perfection: Place the rolls in the preheated oven and bake for 15 minutes or until the tops are golden brown. Keep an eye on them during the last few minutes to avoid over browning.

Serve and Enjoy: Once baked, remove the rolls from the oven and immediately brush them with melted butter for a glossy, rich finish. Serve warm and enjoy the soft, buttery flavor that makes these rolls irresistible.
