Pistachio
Pistachios add slight sweetness, color, and richness to many dishes.
Pistachios are the seeds of a small tree native to Iran and Central Asia, with shells that split open as they ripen. They taste sweet and buttery with a light floral, grassy edge and a whisper of bitterness, and their bright green colour makes any dish look special.
Cooks love pistachios in both sweet and savoury cooking. They are the heart of baklava, kulfi and Sicilian cannoli, a crunchy crust on fish and chicken, and a jewel-like scatter over pilafs and salads. Cardamom, saffron, honey and citrus bring out their best.
Flavor profile
Aroma: sweet, grassy
Good to know
Origin: Middle East
Forms: whole, shelled, milled
Season: Harvested in late summer and early autumn; available year-round.
Nutrition: A source of protein and fat; pistachios are a tree nut allergen.
Storage: Keep pistachios airtight in a cool, dark cupboard for up to three months, or in the fridge for up to a year. They freeze well for longer, sealed tightly. Light and warmth fade their colour and turn their oils stale. Rancid pistachios taste bitter and smell like old oil, so discard them. Pistachio paste should be refrigerated after opening.
How to use pistachio
Baking Softness
Natural oils enhance dough softness by retaining air and moisture as they bake.
Crunchy Coatings
Pistachio crusts create crunch while oils intensify flavor when heated.
The science of pistachio
- Pistachios are green because the kernel holds chlorophyll, along with yellow lutein. High heat breaks chlorophyll down, so toast gently, around 160°C (325°F) for 6–8 minutes, to keep the colour vivid.
- The purple-red skin around the kernel gets its colour from anthocyanins. Blanching briefly and rubbing off the skins reveals the brightest green nut for desserts.
- Like other oily nuts, pistachios brown through the Maillard reaction when heated, adding roasty notes. Their natural oils also carry flavour into doughs and crusts, which is why a pistachio crust tastes richer once baked.
- In brittle and praline, sugar caramelises around the nuts and sets glassy once it reaches the hard-crack stage near 150°C (300°F). The nut's fat keeps the brittle from tasting harsh.
- Pistachios belong to the same plant family as cashews and mangoes, which matters for allergies: a cashew allergy often comes with a pistachio allergy too.
How to choose pistachio
Look for the greenest kernels you can find; the deeper the green, the better the flavour and the more striking the colour. In-shell pistachios should be partly split open and feel heavy. For baking, buy shelled, unsalted nuts so you control the seasoning.
