Pistachio butter is a creamy spread made from roasted or raw pistachio nuts that are ground into a smooth, paste-like consistency, similar to almond or peanut butter. It offers a unique nutty flavor and is considered a nutritious and flavorful alternative to other nut butters. Storage: Store pistachio butter in a cool, dry place or in the refrigerator to extend its shelf life. Like other natural nut butters, pistachio butter may separate over time, with the oil rising to the top. Stirring the butter before use can help recombine the oil and solids. Allergen Information: Pistachio butter is not suitable for individuals with nut allergies, as it contains pistachio nuts.
