I have a Welbuilt bread machine and a recipe that has always worked wonderfully in the past. The bread machine only has 'french', 'sweet', 'white', and 'manual' modes.

I would like to experiment with flavors. Therefore, I would like to substitue one cup of freshly ground red whole wheat berries for one of the three cups the original recipe calls for.

The original bread machine recipe:

2 1/2 tsp dry yeast

3 cups of flour

1 1/2 tsp salt

1 1/2 tsp sugar

1 1/2 tsp shortening

1 1/2 cups plus 2 tbsp. lukewarm water

Can I just go ahead and substitute one of the three cups of flour for one cup of freshly grounded red whole wheat?

What mode would I use?

Do I have to modify the other ingredients of the recipe to accomidate the one cup of whole wheat flour substitution?
