Preheat your oven to 200º F, then turn it off. Prepare a baking sheet by lining it with parchment paper.
Bring all ingredients to room temperature. In the bowl of a stand mixer (recommended)**, add the wet ingredients (water, yogurt, cider vinegar, egg yolks, oil, honey) and mix until combined.
Gradually stir the gfJules Bread MIx + yeast packet into the wet until fully integrated.
Mix 1-2 minutes more on medium speed to ensure all ingredients are fully incorporated.
Once the dough is combined, divide it in half and divide each half into three equal-sized balls (6 balls total). Roll each ball out into an 18-inch coil or log on a clean, flat surface dusted very lightly with gfJules All Purpose Flour.
Pinch together one end of each coil, scoring and wetting them slightly with water to help them join together at the top, then braid them, finishing by connecting them at the other end.
Gently transfer braid to the parchment-lined baking sheet. Repeat for the second set of three balls. You may divide the dough into as many balls as you like, counting on at least 3 balls per loaf. Roll each to equal lengths of coil and braid into 1 or more loaves.
In a small bowl, mix the extra egg together with a tablespoon of water or milk and brush over each loaf well, coating the entire top surface. Sprinkle the fruit or any toppings at this point, then place the tray (covering the loaves with wax paper or parchment sprayed with cooking oil) in a warm location for 30 minutes.
Once risen at least slightly, place the uncovered tray in an oven preheated to 350º F (static) or 325º F (convection) for 20 minutes (less time for smaller loaves). A toothpick inserted into the center of the bread should come out dry or with dry crumbs when done.
(Optional: instead of baking right away after rising, brush again with egg wash or spritz with water and cover loosely with plastic wrap. Refrigerate overnight. Remove to the counter while pre-heating your oven. Remove plastic wrap and bake as directed.)
Remove to cool on a wire rack.
