Prepare the Oatmeal: Combine rolled oats with boiling water, allowing them to soak up the liquid.
Mixing the Dough: In a large mixing bowl, mix water, prepared oatmeal, optional spices, and honey with the hard wheatberries flour until well combined. I mix for five minutes, and let the mixture rest for 10 minutes.
Incorporate Yeast and Salt: Add instant yeast and sea salt to the dough mixture. Knead until the dough achieves a smooth, elastic consistency—a hallmark of well-developed gluten.
First Rise: Cover the dough and let it rise in a warm place until doubled in size.
Shaping and Second Rise: Shape the dough into a loaf and place it in a 9x5 bread pan. Allow it to rise again until it reaches just above the rim of the pan.
Baking: Preheat your oven to 375°F (190°C). Bake the bread for approximately 35 minutes or until the crust turns lightly golden. Then, lower the temperature to 330°F (165°C) and continue baking until the internal temperature of the bread reaches 190°F (88°C).
