Mix together the yeast, sugar and water. Set aside for 10 minutes until the yeast is activated and frothy.
Add the oil, salt and 2 cups of flour to the yeast mixture and combine.
Add the flour a little at a time until the dough begins to come together and leaves the edges of the bowl.
Empty the dough out onto a kneading surface and knead for 7-8 minutes until it begins to feel smooth and oh-so-silky. Transfer the dough into a lightly greased bowl and cover with a thin cloth or plastic wrap. Let the dough rise to double its size (about 1 hour - I think it''s so short because of the large amount of yeast).
Gently deflate the dough and turn out onto the kneading surface. Divide the dough into 12-14 equal parts and roll each into a ball. Place them on a baking tray a couple of inches apart. Cover with a damp cloth for about 45 minutes. Preheat oven to 200 deg C.
Bake for 12-15 minutes until golden brown. For hard crusted rolls, spray water couple of times for the first 4-5 minutes while baking. For a soft crust, brush the hot rolls with some melted butter as soon as they come out of the oven.
