Julia Child's White Bread
Let it sit for 5 minutes until creamy. Put the yeast mixture, rest of the water and 3 1/2 cups of the flour into the mixer with the dough hook.
Increase speed and scrape down the sides til the dough comes together. (If it doesn't add a tbsp of flour at a time til it does.)
Back in mixer add butter 1 tbsp at a time (dough may come apart, but mixing will pull it back together).
Butter 2 loaf pans.
Roll out into a 9 x 12-inch rectangle.
Drop in the loaf pan seem side down, and repeat.
Preheat the oven to 375°F and put the rack in the center of the oven.
