Rehydrate the yeast in the warm water.
To the warm milk add the butter and egg.
In the bowl of a stand mixer, mix the flour, sugar, salt, water, and milk mixtures.
With a dough hook; mix just until it becomes a ragged ball.
Let rest 15-25 minutes.
After resting; knead 10-12 minutes, adding a little flour if the dough is too sticky.
After kneading; cover and let rest until doubled in size.
Preheat oven to 350ºF.
Turn the dough out on your bench; divide into 16 pieces.
Shape the pieces into balls and place in a greased 16x9" glass baking dish.
Cover and let rest, until buns double in size.
Bake for about 25-30 minutes, or until the internal temp is at least 190ºF.
