Pistachios are the seeds of the fruits of the Pistachio vera tree, which produces clusters of small fruits that gradually harden and split, exposing the seed within. Though they're seeds, they're considered nuts in culinary settings and classified as a tree nut allergen..
Moreover, what kind of nuts are pistachios?
Pistachios. The desert plant called the pistachio tree is a member of the cashew family, and as we've mentioned before: cashews are not a nut. The food that we think of as a pistachio nut, is actually the seed of the pistachio tree, shown here.
Beside above, which nut is not really a nut? True nuts include pecan, sweet chestnut, beech, acorns, hazel, hornbeam and alder. Peanuts, almonds, pistachios, cashews, horse chestnuts and pine nuts are not nuts. So the health warning on a packet of peanuts (“may contain nuts”) is, strictly speaking, untrue.
Secondly, why is a pistachio not a nut?
It's not actually a nut. While we call them nuts, pistachios are the seeds of a fruit that grows in bundles (like grapes). Once the fruit is wrinkled and soft, each pistachio is harvested and when fully ripened, its shell will split, exposing the nut inside.
Can I eat pistachios if I'm allergic to peanuts?
