My grandfather invited me to pick pine nuts with him. We went to the same place he took me jack rabbit hunting as a kid. He told me when the nuts get ripe, the cones opens up and they fall on the ground. He said all we have to do is pick them up.
After a few hours of picking I said, "Grandpa, do know the new technique they use these days sort out the best ones?"
He said, "No, what is it?"
I said, "You put them in water and if they float they're not going to taste so good!"
