Pour the warm water into a large mixing bowl. Sprinkle the yeast over the top and let sit for about 5 minutes, until the mixture looks cloudy. Whisk briefly.
2 cups warm water, 1/2 oz active dry yeast
Add the salt, sugar and vegetable oil. Whisk for about 1 minute, until the salt and sugar have dissolved.
1 tbsp salt, 1/2 cup granulated sugar, 1/4 cup vegetable oil
Using a wooden spoon, stir in the flour 1 cup at a time. Transfer the dough to a lightly floured work surface and knead for approximately 3 minutes, until soft and pliable. Add only enough extra flour to prevent sticking.
5 cups all-purpose flour
Lightly oil a clean, large bowl. Add the dough and turn to coat with oil. Cover and let rise in a warm spot for about 1 hour, or until doubled in size.
Generously grease a 9×13-inch baking dish. Transfer the dough to a lightly floured surface and gently knead for 3–5 minutes. Divide into 15 equal pieces and shape each into a ball. Arrange in the prepared dish in 3 rows of 5.
Cover and let rise in a warm spot for about 2 hours, or until the rolls have doubled in size and look puffy.
Toward the end of the second rise, preheat the oven to 400°F. Gently brush the tops of the rolls with the beaten egg, taking care not to deflate them.
1 egg
Bake for about 20 minutes, until golden brown. Separate at the seams and serve warm with butter, honey or maple syrup.
