I left the cooked bread behind for Jeff to enjoy with the crew, then I took home and baked the dough we made on set. Everyone was happy.
This bread has good chemistry: the baking soda is activated by the acidic buttermilk, giving rise to a simple traditional bread. If you don't have buttermilk in the fridge do this: put 2 tbsp plain white vinegar into a 2-cup measure, then fill with milk to the 2-cup mark. Stir well and let sit 5 minutes to thicken.
It's important to cut the bread before baking ~ a deep sharp cut that allows the bread to "bloom" in the oven and rise up crusty and brown. I cut mine with a serrated bread knife. If you do not slash deep enough, the centre of the bread may be under cooked.
4 cups all purpose flour (or 3+1 cup whole wheat flour)
1 tbsp sugar (optional)
1 tsp salt
1 tsp baking soda
2 cups buttermilk
1. Hold back 1/2 cup of flour. Blend the rest of the flour with the sugar, salt and baking soda.
2. Pour the buttermilk onto the flour. Mix quickly with a fork to make a sticky dough.
3. Turn the dough onto a floured surface and knead by hand, using the extra 1/2 cup of flour as needed to flour your hands and prevent sticking. Work quickly, kneading as little as necessary to get a soft smooth dough that is no longer sticky, about 2-3 minutes.
4. Place the ball of dough on a baking sheet and press to flatten the top. Slash the dough with a knife, cutting a fat inch (~3 cm) deep.
6. Bake at 425F for 35-40 minutes. When cooked, the bread will be quite brown and a good tap on the bottom will sound hollow. Allow to cool a few minutes before slicing. Eat with butter or jam or both!
