Pistachio

Pistachio is the green-kernel seed of Pistacia vera, a desert-adapted tree long cultivated from Central Asia and the Middle East and now orchard-grown at scale in Iran, California, Turkey, and the Mediterranean. Ripe nuts split their shells naturally—the signature open smile of snack pistachios—while the inner kernel shows a vivid green that pastry chefs treat as colour as well as flavour. Taste is sweet-savoury with a distinctive resinous-nut aroma, excellent salted or folded into sweets. Oil is rich enough that heat and light fade both colour and freshness. Cooks meet pistachios in Persian sweets, baklava, gelato, mortadella, pilafs, and roasted snacks. Bright green pastes usually start from carefully blanched inner kernels; brownish pastes may be older stock or less refined milling. Good kernels are fragrant and green- violet at the core; poor ones are dull, yellowed, or paint-scented. Protect from light and heat; refrigerate or freeze for pastry work. More savoury-aromatic than almond, with colour that is part of the product’s commercial value.
