2packetsactive dry yeast (I used 2 packets Red Star 4 ½ teaspoons)
1tablespoonsugar (I used heaping and would probably use more)
½cupwater (100 to 110 degrees)
4cupsbread flour (King Arthur)(560 grams)
1tablespoonsalt (I recommend 2 ¼ teaspoons)
3tablespoonmelted butter
1 to 1 ½cupsbuttermilk (1 ⅓ cup is about right)
Instructions
You'll need a 9x5 inch loaf pan. Set it aside and grease it while the bread is rising.
Combine the ½ cup warm water, sugar and yeast and let sit until foamy (5 to 10 minutes).
In the bowl of a stand mixer, combine 4 cups of bread flour, salt and butter, then add 1 cup of the buttermilk. Stir with the paddle attachment or with a spoon.
Add the yeast mixture and stir well. Mixture will probably be pretty dry at this point, so add another ⅓ cup of the buttermilk. Attach dough hook and begin kneading. If dough seems heavy and dry and splits, continue to gradually add remaining buttermilk by small spoonfuls. Keep kneading for 5 to 7 minutes or until dough is smooth and elastic.
Turn onto a very lightly floured pastry mat and knead by hand for another 2 minutes or so. This dough should be very slick, firm, kind of bouncy but not sticky at all.
Put the dough in a lightly buttered or oiled bowl, roll in the butter or oil, then cover and let rise in a warm place (closed microwave is always a good bet) until more than doubled in bulk. This will probably be about and hour to an hour and a half.
Form into a rough rectangle, then form into a loaf by folding in the ends and then folding in the sides.
Put the dough in the greased pan. Cover with greased plastic wrap and let rise for another hour or just until it is about 1 inch (in the middle) over the edge of the pan.
Bake at 375 degrees F for about 45 minutes. Let cool for about 5 minutes, then remove from the pan and let cool completely.
