Add water, yeast and 1 tbsp of honey to mixing bowl and stir. (there is half a cup of honey in the recipe, just take a spoonful of honey from the 1/2 cup)
Let it sit until it starts to foam or form bubbles.
Mill the flour. Use a scale to measure 450 grams of red and 500 grams of white wheat berries and mill to get fresh flour. Add Vitamin C, vital wheat gluten, and salt to the fresly milled flour.
Add honey, egg yolks and vinegar to the mixing bowl.
Add the dry ingredients. On low speed slowly add the dry ingredients to the mixing bowl. Let the dough knead until combined to get the gluten developed. Add the oil slowly to the bowl. Now give it some time to mix until all the oil is incorporated into the dough. It will take a minute. The purpose of adding the oil last is because fat inhibits the development of gluten. By adding it last you are giving the dough a chance to develop gluten before adding fat.
Knead for 8-10 minutes. Do a window pane test to make sure you have good gluten development. To do this, take a small piece of dough and gently stretch and pull it. If you can stretch the dough enough to form a thin translucent 'windowpane' then the dough has enough gluten developed. If it rips right away, you need to continue kneading and then test again.
