"<p>Christopher Kimball, founder of Christopher Kimball’s Milk Street, spent decades perfecting this recipe for foolproof pie dough that’s both tender and easy to work with. “We tried to speed up the chilling of the dough by popping it in the freezer,” he says, “but that didn’t give the starch in the dough enough time to get sufficiently hydrated.
