Pieometry: Modern Tart Art and Pie Design for the Eye and the Palate

Ko earned Instagram fame for her gorgeously crafted pies, and in this pun-heavy guide (“Let’s get this tarty started”) she generously shares her tricks. “Spoke Signals” (with spiraling strips of dough that form a hub at the center) was Ko’s Instagram breakout and is typical of her geometric genius. Crusts range from basic to options that incorporate Oreos and sprinkles and a blue version colored with butterfly pea flower. Some combinations are surprising—“Block and Awe” pairs cherry filling with two doughs, one marbled with Nutella and the other made with beets—but the visual effects are always brilliant. In “Pink Out Loud,” dragon fruit powder turns a lime-curd filling a bright magenta that contrasts with geometric speckled dragon fruit-flesh tiles; in “Floral of the Story,” each hexagon in a clever honeycomb design of dough encases an edible flower. Savory options include a miso and carrot pie topped with banana-shaped dough curls. The instructions for more ambitious woven crusts, including a three-tone Aztec-style design, are precise and accompanied by helpful photos. This is a no-brainer for Ko’s many fans who are eager to learn the secrets behind her show-stopping work, or any baker looking to add some confectionery flash to their repertoire. (Oct.)
