My 75th experiment: Oat bran bread

Sometimes I just get a little exhausted thinking about new experiments. So here is just one of my lazy experiment with oat bran, which turns out at the end to cause more work than not.

Recipe: Oat bran bread (1 medium loaf)

Ingredients:
Dough with delayed fermentation
- 2 cups KAF bread flour
- 1 cup oat bran
- 1 cup + 2 TB 1% milk
- 1+1/4 tp salt
- 1 tp active dry yeast
- 1 TB olive oil
Final dough
- dough from delayed fermentation
- 1/2 cup KAF bread flour
- 1 tp active dry yeast
- about 1/2 cup water
- 2 TB olive oil

Procedure:
1. Soak oat bran and yeast in 3/4 cup milk for about 15 minutes.
2. Sieve flour with salt. Then add the soaked oat bran, with liquid into the flour.
3. Mix and knead for a few minutes, adding milk 2 TB at a time, until a moist strong dough is formed.
4. Add 1 TB olive oil, rubbing in.
5. Allow to chill overnight.
6. Allow dough to rise to room temperature. Then adjust hydration with additional water, and flour, and add an extra 1 tp of proofed yeast.
7. Allow to rise until double.
8. Bake at 350F. After the top is golden (about 15 minutes), cover with foil and bake until internal temperature reaches 190F.
9. Cool before slicing.

Observations:
1. In this experiment, I want to test out delayed fermentation. After working on the dough for a while, I've come to realize that the ratio of bran to bread flour (1:2) is probably too high. In my previous experiments, this ratio result in breads that are very dense, and are pleasant to eat only when there is some extra ingredients, such as pineapple, or cheese.
2. Milk tend to disintegrate when left too long. This limits the length of delay I can afford for fermentation.
3. Apparently, oat bran absorbs so much water that the dough remains really tough even after adding ample water.
4. This loaf turns out pleasant in color and aroma. There is no additional sugar in the loaf. The taste is plainly salty, but with a rather rich flavor of oat. It's pleasantly simple. I like it.
5. The challenge in this loaf is its denseness. The crumb is heavy. The holes in the loaf simply aren't big. It might do better if the hydration level is a little higher, but I am not sure about that.
6. Soaking the bran before use seems to improve the texture of the loaf. The crumb feels softer.
