The recipe calls for all-purpose unbleached white flour but I've tried subbing 1/2, 1/3, and 1/4 bread flour. More or less same results.
Kneading for 15min.
Maybe I should make the recipe as-is to see what happens?
I hadn't previously calculated hydration as was using a canned recipe, but the math comes out at 66.4%
This is the recipe I'm using.
Frank's White Bread, Two 2 pound loaves Stand Mixer for kneading
All ingredients at room temperature
25 Ounces tap water
38 Ounces bread flour
2 Tbs sugar
1 Tbs canning/pickling salt
1/4 Cup dry milk powder
14 Grams instant yeast
4 Tbs softened butter
Blend all dry ingredients in mixing bowl with whisk.
Mix dry ingredients and water at low speed in mixer bowl. Hydrate for 5 minutes.
Knead for 3 to 5 minutes on speed 2 until the dough is smooth.
Slowly drizzle in butter. The dough will come apart. A little flour can be added after a minute to help pull the dough back if necessary.
Total kneading time 8 to 9 minutes.
Turn dough out on lightly oiled surface and shape it into a ball then place back in oiled mixing bowl.
Turn dough so it is completely coated in the oil, cover in oiled plastic for 45 minutes to an hour, at room temperature, till it has doubled in size.
Deflate the dough and turn out onto a lightly oiled surface. Cut into two 32 ounce loaves.
Shape loaves, deflate bubbles that appear.
Drop in oiled loaf pans.
Cover the loaves with oiled plastic wrap and allow to rise at room temperature, about 35 to 45 minutes.
Preheat the oven to 375°F with the rack in the center of the oven.
Bake for 40 - 45 minutes, 205° to 206°F internal temperature.
