Nuts

Kernel

The pine-nut kernel is the soft, ivory seed freed from the hard shell of edible Pinus species. Shape and flavour shift with species: Mediterranean pinoli are plump and buttery with pine perfume; Korean-pine kernels are longer, more triangular, and often milder until toasted; pinyon seeds are small and intensely oily. This is the form pesto, pilaf, and cookie recipes mean by “pine nuts.” The oil is delicate—warmth and air turn kernels flat within weeks if ignored. Sort out any dark or paint-scented pieces before grinding. Toast in a dry pan only until the first blush of colour, then pour onto a cool plate. Fresh kernels smell sweet and resinous; rancid ones smell like cardboard. Always refrigerate or freeze opened packs. Species labelling on the bag is worth reading: cheaper bulk kernels are not automatic failures, but they are not interchangeable with premium Italian pinoli in a tasting-room pesto.
