In a large bowl, add yeast and 1 teaspoon of granulated sugar. Add warm water (100-110F) and stir gently until yeast is completely dissolved.
To the large bowl, add the remaining granulated sugar, salt, butter of your choice, egg, milk of your choice (100-110F), and 2 cups of all-purpose flour. Using an electric mixer on low speed, beat until smooth. Add in the remaining 2 1/4 cups of all-purpose flour and use your hands to mix it together to form a soft dough.
Place dough onto a floured working surface. Knead with your hands for 6-8 minutes.
Place dough in a large greased bowl and cover with a dish towel. Let dough rise in a warm place for an hour (see "Turning Oven Into Proofing Box" instructions above).
Remove the dough from the oven. Remove the dish towel and punch the dough down.
Split the dough in half. Roll each half into a 12" diameter circle. Using a pizza cutter or a butter knife, first cut the circle into four quarters. Then cut each quarter into thirds to yield 12 triangles. Starting from the outside (perimeter) working your way in (center), gently roll the triangle. Curve ends inward to form a crescent, if desired.
Grease a large baking sheet with vegetable oil. Place each roll point side down onto the greased baking sheet, leaving plenty of room between. Cover baking sheet with a dish towel. Let rolls rise in a warm place for 30 minutes (see "Turning Oven Into Proofing Box" instructions above). NOTE: If your oven is large enough, you can place both baking sheets in at once, and let the crescent rolls rise for 30 minutes. However, if your oven is small, you will have to do each baking sheet separately. Just be sure to double check your oven temperature and humidity between sheets if this is the case. Remove the rolls from the oven after the second rise, and gently remove the dish towels.
Preheat oven to 350F. Bake crescent rolls for 10-12 minutes, or until golden brown. Transfer rolls from baking sheets to wire racks to cool. Once cooled, either store in the refrigerator or in the freezer. In the freezer, they are good for about a month.
