Pawpaw fruit (also called Ohio banana, Kentucky banana, or custard apple) grows wild in natural forests in North America. It resembles mango in shape and texture and, like mango, is chock full of vitamin C. Paired with black walnuts, pawpaw cookies are a delicious snack that you can make from locally-acquired ingredients. Who knows? You might have one of this nutritional and culinary treasure trove in your own backyard!
