Step 2
To the bowl with the milk and yeast, add 5 tablespoons melted butter, 1/4 cup granulated sugar, egg, egg yolk and salt. Mix until the egg yolks are broken up and incorporated. Add three cups of flour, one cup at a time, mixing between each addition until incorporated. Add approximately 3/4 cup of the remaining one cup of flour (the additional flour will be used to dust the surface when you roll out the dough). Tip the shaggy dough out onto a clean work surface, and knead for 8 minutes. The dough will be smooth and elastic after kneading.
