Combine fennel seeds, cumin seeds, caraway seeds, cracked wheat, butter, molasses, and orange zest in boiling water.

Soak the mixture for 1 hour to pre-soak the cracked wheat and release flavors.

Add the seed mixture, baking soda, rye flour, bread flour, dry yeast, gluten flour, and powdered buttermilk into the bread machine pan in the order suggested by the manufacturer.

Select the cycle for White Bread and the Light Crust setting.

Start the bread machine and let it complete the cycle.
