With the stand mixer running on low speed, add the honey into the yeast mixture, add egg,+ egg yolk, melted butter, salt, and 3 cups of flour. Beat on low speed for 1 minute, then add remaining 1/2 cup of flour. Beat on low speed for 1 minute as it all combines. The dough should be thick, yet soft. And only slightly sticky. It should pull away from the sides of the bowl as it mixes. When it does, it is ready to knead.
