In nature, pine nuts are found inside the cones of umbrella pines, and their harvest generally takes place in the period between the months of May and July, the quantity of which - in relation to the cone - is particularly limited, with a proportion of approximately 1 to 30, which can essentially be translated into one hundred grams of fruit for thirty of pine cones. Pine nuts have a very high caloric intake, especially keeping in mind that they are characterized by a notable presence of proteins and fats, as well as calcium.
