What are pine nuts?
Pine nuts are the edible seeds that are harvested from certain species of pines. They’re also called pignolias. They grow between the scales of the pine cones. The thickness of the shell varies according to the species of pine. They are typically elongated or teardrop shaped. Pignolias are ivory-colored and generally measure 1/2″ in length. The extracted seeds have a soft texture and a buttery flavor. They can be eaten raw or toasted. Toasting the seeds intensifies their flavor and adds a slight bit of crunchiness to the seed.
Pollination and seed development
There are approximately 20 species of pines that produce seeds that are large enough to be harvested for consumption. The maturity process for the seed varies according to the exact species. It takes a stone pine seeds 36 months to reach maturity. The growth process for some American species begin in early spring with pollination. A small cone will begin to develop around mid-spring and by the end of the summer a premature cone will develop. This premature cone will remain dormant until the following spring. Growth will then resume and continue until it reaches maturity at the end of the summer.
Elevation and pine cone production
There’s a definite correlation between the quantity of pine cone production and the elevation at which it is grown. The ideal elevation level for the American Pinyon pine cone is 7,000 feet. It can be grown successfully at elevations between 6,000 feet and 8,500 feet. The development of cones is more prolific in areas where humidity is high. Therefore, lower elevations are more conducive to cone development and growth. The cones need moisture for nourishment and growth. Lower elevations are also less susceptible to substantial drops in temperature and various other dramatic weather conditions that can adversely affect the growth of the seeds.
Where are pine nuts grown in the United States
Edible pine nuts can be grown in various locations in the United States. To successfully grow edible pines in the United States, it’s essential that the hardiness zone for the species match the area where the tree is planted. For example, the Korean Pine and Swiss Pine are compatible with zone 2 growing conditions but the Pinyon Pine requires the conditions found in zone 4. New Mexico, Nevada, Utah and Colorado are states that are well known for growing pine nuts.
Harvesting Pine Nuts
Pine nuts are typically harvested by hand. The cones can be dislodged from the tree using a hook or a commercial tree shaker. Once the cones are picked up they must go through a curing or drying process before the seed can be extracted from the cone. When the cones are dry, they are broken open and the seeds are picked out of them. Pine nuts have a shell that must be removed. The toughness of the shell varies with the species of pine. Generally, the shell can be removed with a nutcracker. The seed will last for several months if frozen. Toasted seeds should be consumed within a couple of weeks.
