I start the day before I want to bake. I make a preferment in the morning which is3/4 cup sourdough starter (doubled and bubbly not fallen yet), 1 cup water, 1 1/3 cup flour. Now I’m a rough measure person so I try to measure the water and the rest is eyeballed and by feel. Before bed, I make the dough. So to the preferment (which should look bubbly by now) I add lard, cane sugar, salt, milk (or buttermilk if you just made homemade butter), and flour (Start with 4 cups and add more as you knead until it feels like a soft dough, not sticky but not dry.).
Cover your bowl with a loose lid or wet tea towel and let sit overnight.
The next morning, you’ll have a big beautiful dough. Punch it down and divide into two equal balls.
Now to shape the dough, press out into a rectangle, stretching the ends and edges slightly. Roll up the dough and tuck in the ends. Pull the dough gently toward you to build tension and pop into a loaf pan lined with parchment paper. Do the same to the next ball.
I like to put my pans into a plastic bag and balloon it so they have room to rise without touching the bag. Let sit for 2-3 hours. By this time, the loaves should be doubled in size.
Preheat the oven to 375 degrees F.
Slash the top with a sharp knife and bake for 20 minutes. Then flip pans and bake for another 20 minutes. Your internal temp should be 190-200 degrees F when it is ready to come out of the oven.
When it’s done, leave in the loaf pan for 10 minutes and brush the top with melted butter to create a nice, soft, buttery crust.
Let it cool the rest of the way on a rack, slice, and enjoy!
