In a medium bowl add the flour, salt, and sugar and whisk to combine well. Add the yeast and whisk one more time. Add the yogurt, melted butter and water, and either with your hands or with a stand mixer fitted with the paddle attachment mix on medium speed for about 3 minutes. The dough should be a little bit sticky. Cover the dough and let it rise in a warm spot for 1 hour.
While the dough is rising prepare the garlic butter: Mince 3 garlic cloves and mix them with melted butter and Italian seasoning.
When the dough is ready, divide it into two parts and shape each part into a lag. With a sharp knife cut the lof into 11 1-inch stripes. Roll each strip into ropes. Tie each into knots. You can tuck the two end of the knots underneath the knot or leave them out.
Place the knots on a baking tray or cast iron pan,cover them with a plastic wrap or kitchen towel and let them rise at room temperatire for 20 to 30 minutes
Preheat the oven to 350℉ (180℃)
Brush the knots with garlic butter (but reserve half of the butter for when the knots come out of the oven). Place them in the oven and bake for about 20 to 25 minutes or until golden brown on top.
Remove from the oven and brush the warm knots with remaining garlic butter
Spribkle with parmesan cheese and/or parsley, if using.
