Remember red pistachios? Up until the 1970s, it was almost impossible to find pistachios that didn’t leave fiery-red powder on your fingers.

So what happened to red pistachios? And where did they come from in the first place? Read on to find out.

Who was the first to make red pistachios?

There are two competing stories that explain why pistachio shells used to be red.

In one version, the crimson hue originated with a pistachio vendor named Zaloom in Brooklyn, New York, around the turn of the 20th century. He decided to dye his nuts to make his products stand out from the competition. According to the tale, Zaloom’s dyeing process quickly took hold and became the standard for pistachios in the United States.

Dr. Bob Klein, the former manager of the California Pistachio Research board, shared a slightly different version with farmprogress.com. Pistachios were colored red to cover unsightly but natural markings on the nuts’ shells, he explained. American processors would dye the nuts, which were mostly imported from Iran, before distributing them.
