Pistachios have a rich, earthy taste, and while they aren’t quite as versatile as other nuts, they can be eaten a number of ways:
As a snack. Eating pistachios plain is arguably the most common way they are enjoyed, either raw or roasted. Both in-shell and shelled pistachios are available in grocery stores.
Over salads. Shelled pistachios (either whole or chopped) are often sprinkled over lettuce or arugula salads. Pistachios can also be puréed and mixed with oil and herbs to make a creamy salad dressing.
Ground into sauces. Ground pistachios are popular as a base for sauces and dips, like pistachio-yogurt sauce.
Added to bread dough. Ground pistachios can be added to bread dough to give it a thicker texture with extra protein.
In desserts. Chopped pistachios are commonly mixed into or sprinkled atop desserts like ice cream, cake, truffles, and pastries. Pistachio flavoring is also a common dessert ingredient it is most well-known as the flavoring for pistachio ice cream and gelato, but it is very versatile and can be mixed into almost any dessert.
