"I grew up watching my mom make pies," says Grant Achatz. "My father would always envy her amazingly tender and flaky crusts. He is a great cook, but he could never quite make a piecrust like she can. Her crust rules, and I understand now that the secret is finesse, and genetically cold hands." Achatz's pie, inspired by his mom's, is as straightforward as it gets, with a melt-in-your-mouth all-shortening crust and a lightly sweetened pear filling with just a hint of spice.
