Add the egg and stir in a all purpose flour in batches. Mix as you stir in each batch. Continue to mix for 3 minutes, you want a soft dough to form.
Transfer dough to a clean surface and knead for 5 minutes, knead with a mixer if that is what you prefer to use. If using a mixer, start on low speed and increase speed to medium. The consistency of your dough should be elastic and soft.
Lightly grease clean bowl and transfer the dough into it. Cover a towel or plastic wrap and leave to rise for 60 minutes.
Gently punch down the dough and divide it into 2. Now you have 2 doughs. Divide each dough into 9 dinner rolls, altogether making 18 rolls. Using a baking pan, line the rolls in 3 rolls of 6. If using 2 pans, line the rolls in 3 rolls of 3 for each pan. Cover with a plastic wrap or towel and leave to rise for 40 minutes.
Preheat your oven to 375F, once the rolls have risen or doubled in size, pop them into the oven and bake for 15 minutes or until golden brown and cooked through.
Take out of the oven and butter the top. You can also use melted butter to brush the top of the rolls. Leave to stand for 10 minutes and serve.
