The twenty-eighth Bread Baker's Apprentice challenge (from the book by the same name authored by Peter Reinhart) is Potato Sweet Bread (Rolls), and is found on pages 219-221.
This is a two-day dough: a small amount of time on the first day to make the biga and let it rise for a couple of hours and then into the refrigerator for an overnight stay. Ingredient list for biga: bread flour, yeast, water.
The next day you take the biga out to warm for about an hour and mix it with the other ingredients for a two hour rise, form into bread or rolls, let it rise another hour or two. The dough made 18 rolls of 2 ounce size and they were brushed with olive oil before they baked for 25 minutes. Ingredient list for bread dough: Bread flour, salt, pepper, yeast, mashed potatoes, olive oil, rosemary, and water. Delicious. Definitely a repeat, one of my favorites so far.
You can visit the main group and marvel the breads. I'm getting there...Slow and Steady. Our next challenge: Pugliese, found on pages 222-226.
