Marie, I have lots of recipes. The one I use for my husband and I has 30% whole wheat, and 5% rye. Most people like all bread flour. That's what my grandkids and a lot of people like. I'll give you both. Same method for both.
Sourdough Starter - I keep 15g in fridge. Night before I take out and feed with 15g flour (50/50 all purpose and whole wheat) and 15g water.
Next morning I feed with 45g flour and 45g water. When double in 4-6 hours I take 95-100g and put the rest back in fridge without feeding.
Thirty-five Percent Whole Grains Bread:
295g bread flour, 137g whole wheat, 23g rye flour, 340g warm water, 10g salt, and 97g starter. Mix all together and let sit for an hour.
Every 30 minutes do a set of stretch and folds for 2 hours.
Let sit 2 hours.
Pre shape, bench rest for 20 minutes, then final shape. Put into banneton and fridge overnight. The fridge develops flavor so if you want a more sour taste you can leave in their up to 3 days. I don't like sour taste so I only leave mine overnight or 12 hours or so.
Next morning or whenever you want bake at 475* covered for 20 minutes, then 15 minutes uncovered.
For All Bread Flour:
500g bread flour
350g water
9g salt
Good Luck,
Mary
