Step 1

Weigh your flours; or measure them by gently spooning into a cup, then sweeping off any excess.

Step 2

Combine the flour with the remaining ingredients, starting with the lesser amount of water, and mix and knead to make a smooth, elastic dough, adding more water as necessary. This should take about 10 minutes by hand, or 7 minutes using a stand mixer on low speed. Add more water as necessary.

Step 3

Place the dough in a lightly greased bowl, cover it, and let it rise for 45 to 60 minutes. It'll become quite puffy, though not necessarily doubled.

Step 4

Transfer the dough to a lightly floured work surface, deflate it gently, and shape it into a 9" loaf.

Step 5

Place the loaf in a lightly greased 9" x 5" loaf pan, cover the pan, and let the dough rise for 45 to 75 minutes, until it's crowned 1" to 1 1/2" over the rim of the pan.

Step 6

Towards the end of the rising time, preheat the oven to 350°F.

Step 7

Bake the bread for 35 to 45 minutes, until golden brown on top, and a digital thermometer inserted into the center registers 195°F to 200°F.

Step 8

Remove the bread from the oven and turn it out onto a rack to cool.

Step 9

When the bread is completely cool, wrap it in plastic and store at room temperature for several days; freeze for longer storage.
