( Kneading is the key guys. Do not compromise on this step )If using a stand mixer, knead on medium speed for 6-8 minutes )Lightly oil a bowl and transfer the dough in the bowl.Cover the bowl with a moist cloth and keep it in a warm place for 2 hours, till the dough doubles in size.Lightly punch the dough.Divide the dough into 15 equal pieces.Lightly oil your work surface and roll each piece into a ball on it.Roll each ball into a 7-8 inch long cylinder and then bring the ends together to make a knot.Grease a baking sheet and line the knots on the sheet keeping a distance of 1 and ½ inch between each knot.Cover with a lightly greased cling film.Keep in a warm place for an hour.Pre heat the oven to 200 degrees C.Set the oven on TOAST MODE where both the heating elements with work. ( In my oven it is represented by two parallel lines )Mix egg white with a tbsp of water.Lightly brush the egg wash on the knots.Bake for 15- 20 minutes, till slightly browned form the top.Meanwhile heat butter and olive oil in a pan.Add garlic when the is hot.Cook till garlic is slightly browned.Add parsley and switch off the heat.When the knots are done, pour the butter mixture over them.Grate Parmesan over the hot knots.These are best served straight from the oven.
