Tofu puffs are fried cubes of soft tofu that, when cooled, become slightly chewy and spongy. The texture holds up well in this kung pao preparation. You can buy tofu puffs in packages at an Asian market. They can be labeled bean curd puffs, soy puffs, tofu pouches, tofu beignets, tofu soufflé—and likely other terms that are country specific. While making your own tofu puffs (recipe follows) is an extra step, the freshness can make a difference in the final dish. - Hsiao-Ching Chou (c)2021 by…
