Mill your rye berries in a grain mill on the fine setting.
In a small pot, warm the water to about 195 degrees F.
In a large mixing bowl, add the warm water, the flour, the salt, and the instant yeast.
Mix until well combined. This will be a very sticky dough.
Prepare a loaf pan by spraying with oil or lining with a piece of parchment paper lightly sprayed with oil.
Using a rubber spatula, scoop the dough into the prepared loaf pan and spread out evenly in the pan.
Cover with plastic wrap or a damp tea towel and let rise for 1 1/2 - 2 hours or until the dough is nearing the edge of the pan.
Keep in mind, this bread will not have the super high rise you get with bread made with all purpose flour or bread flour.
Preheat the oven to 350 degrees F.
Bake the loaf for 35-40 minutes or until the internal temperature is 200-205 degrees F read with an instant read thermometer.
Allow the bread to cool completely before slicing.
