Pine nuts are the edible nuts produced by Pinus species, found on the woody scales of female pine cones. Their removal is labor-intensive, which makes the nuts expensive relative to other tree nuts. Eaten raw or roasted, they are used in savory and sweet dishes, famously in pesto, salads, baked goods, and confectionery, contributing a delicate, buttery flavor and tender texture. In food quality, pine nuts are graded by size, uniformity, and freedom from rancidity, since their high oil content makes them prone to oxidative spoilage. Proper cool, dry storage and protective packaging preserve their flavor, supporting their premium positioning in global nut markets.
