This pistachio cream is best when made with raw, unsalted pistachios for a naturally vibrant color and smooth texture. If your pistachios have skins, you can blanch and peel them for an even brighter green result. For a thinner consistency, feel free to add a splash of milk (dairy or plant-based). Store in a sealed jar in the fridge for up to 10 days, or freeze in small portions for longer shelf life. This cream makes a delicious filling for pastries, spread for toast, or a decadent topping for desserts.
