If one way is better than another, you may be sure it is nature's way.
All pine seeds are edible, but most are too small for humans to bother with.
One method of locating pine species in Mexico used by Dana K. Bailey and Frank Hawksworth in the 1970's was to visit the local food markets and examine the pinenuts for sale and inquire about the location of the trees which were their source. Pine seeds are an important source of food for many animals and in some cases, the animals return the favor by cacheing the pine seeds and thereby inadvertenly planting them. Also many rodents depend on pinenuts for food.
