Did you know that walnuts are the oldest known tree food? Or that they’re the most common nut used in American home-cooked recipes and restaurant dishes?
In ancient Persia, around 7000 B.C., English merchant ships first started trading walnuts along the Mediterranean Sea. Since walnuts were never commercially produced in England, people believe the name “English walnuts” originated from this historical trading. In the late 1700s, some Franciscan fathers from Mexico and Spain brought walnut trees to California, which now produces over 99% of the U.S. supply and over 2/3 of the world’s walnut trade.
