Combine flour, sugar, and salt in your mixer bowl. Toss in yeast (for active dry type, soak it in the warm water first). Add milk and water, then blend until smooth and elastic, roughly 8-10 minutes.

Form a ball with the dough, pop it in a greased bowl, wrap it up, and let it sit somewhere warm for half an hour.

Mix butter chunks with flour until barely combined. Form a 6-inch square with plastic wrap, then cool while your dough sits.

Stretch dough into a 10-inch square. Set the cold butter square at an angle in the middle, fold the corners over like wrapping a gift, and press edges firmly.

Stretch into a 16x8-inch rectangle, fold in thirds like folding a letter. Chill for an hour. Do this rolling and folding twice more, cooling between rounds. After the last fold, cool overnight.
