The big news is that some years ago I stopped using baking soda to raise the sourdough, though that's the traditional Old Settler drill. Soda is good for baking on the fly, because it reacts to the heat of the oven instead of requiring a lengthy stretch of steady, controlled warmth beforehand to raise the dough.
But eventually I succumbed to the richer scent and flavour, and the light, airy crumb, you get from wild yeast.
And it's still a simple and straightforward process, calling for just 20 minutes of hands-on labour, followed by a single rise. So now I do it like this:
YEAST-RAISED SOURDOUGH HERMIT BREAD
1 1/2 cups sourdough starter
About 2 cups all-purpose flour (added by handfuls to optimum texture)
1 tablespoon oil for brushing
shortening or butter for lubrication
Liberally grease a 10-inch cast iron skillet. You can also use a cake pan or cookie sheet, but cast iron gives the best results.
In a large bowl, blend the flour into the starter with a butter knife. When too stiff to stir, continue cutting in flour with the blade until the dough balls easily and is dry enough to work with the hands.
Knead the dough while continuing to add flour as necessary to prevent it sticking to your fingers. (See notes below.) When the dough is smooth, elastic, and dry enough to work lightly without gumming up your hands, roll it into a ball and position it in the centre of the greased skillet.
Pat the ball down to six to eight inches in diameter. Brush the top with oil and perforate the pat in rows with a wooden spoon handle or similar until it's holed all over.
Mark the dimpled pat into 8 wedges with a cleaver, chef's knife, or pastry scraper. Clean up and reseal the edges, cover the skillet, and place the dough in a warm location to work for about 4 hours. (See notes below.)
When the dough has risen sufficiently, preheat the oven to 400 degrees. Uncover the pan and bake the bread on the middle rack for 20 minutes.
When lightly browned, unpan the loaf and place it on a rack to cool for a few minutes. Eat as-is or with any of the usual amendments. (Butter, jam, cheese, herbed oil, sugared berries, etc.)
Keep the fully-cooled pat fresh in an airtight plastic bag. Cold pieces can be microwaved for 30 seconds for a credible impression of just-baked bread.
Notes:
• For a richer bread, make your starter out of bread flour, then knead all-purpose into it as usual.
• I never knead this on a board, as is normal with bread. Instead I tip the bowl up on its bottom edge and knead the dough against the side while turning the bowl with the other hand, like a steering wheel. When the dough is sufficiently dry I hold it up and knead it between my hands. I suspect this technique is rooted in the recipe's origins as sojourner food; there's no other place to knead bread on the trail.
• If you lack grease for lubrication, oil and flour will work as well, but don't skip the flour dusting; the oil alone won't cut it.
• The dough must be tightly covered during the rise, or its surface will dry out and prevent the pat from expanding. I put a tight-fitting lid on the skillet. When baking on a sheet, I invert the now-empty mixing bowl over the pat. Make sure to grease an inch or so of the bowl's upper edge, or any dough that touches will stick.
• For the rise, place the dough somewhere that delivers gentle heat at 80 to 95 degrees. Good prospects include a water heater closet, a purpose-built proofing box, strategic positioning beside a woodstove, or, on a summer day, in reliable shade outdoors. I've also had success in an oven with the light on – usually with the door cracked a certain distance; the light alone can heat the interior to surprising levels – and a sun-heated car, but monitor the temperature carefully and consistently with both. I've also preheated an oven at its lowest setting and then turned it off, returning once or twice to take the dough out and heat the oven again. And I've put a size-appropriate incandescent light in a closet, tote, disused refrigerator, or large ice chest. Again, be very wary – those bulbs throw a lot more heat than you think – and mind the serious fire danger when placing a heat source in a tight space.
• Finally, remember that sourdough will also rise at room temperature if necessary, though it takes longer and results in a sourer, less consistent product.
The history of this bread, as well as traditional ovenless baking methods, are found at the bottom of my original post.
And a last important point: the original soda-raised recipe is still perfectly enjoyable if you've got no way to incubate the yeast; would rather not wait that long; or aren't over-fond of the taste of sourdough, which soda mitigates. It's also good for an upset stomach, among other things.
And I still mix it up for pizza dough.
At some point I'll post a few whole-grain elaborations I've developed over the years. In the meantime, enjoy this simple, thrifty down-home staple, that never fails to bolster my sense of comfort and well-being.
