In our Korean Chicken Wing recipe, which calls for a blend of Wondra and potato starch, you could use just potato starch, but your wings might turn out cakey, and if you leave them out for your party guests to enjoy, they might get soggy over time. Wondra really increases their crispiness, so much so that on the rare occasion that there are some leftovers from the batch made the day before, we eat them cold. Wondra flour is readily available in the U.S., but if you live elsewhere, we recommend ordering it online.
