You will need:
3 cups all-purpose flour
1/2 cup whole-wheat flour
2 teaspoons salt
1 teaspoon instant or rapid-rise yeast
1½ cups water
¼ cup extra-virgin olive oil
1 tablespoon chopped fresh rosemary
In a mixing bowl, add both flours, salt, and yeast and stir together. Pour in the water and several spoons of olive oil and knead on low speed until cohesive dough forms and no dry flour remains, about 5 minutes. Transfer dough to oiled bowl, cover with plastic wrap, and let rest for 30 minutes.
When dough has risen, work it by folding it over itself. Fold dough 7 more times. Cover with plastic and let rise for 30 minutes. Repeat folding and rising every 30 minutes, 3 more times. After fourth set of folds, cover bowl tightly with plastic and refrigerate for at least 16 hours or up to 48 hours.
