How can I quickly shell pine nuts?
This is how you can do it:


Place your nuts into a super-strong plastic food storage bag and close it securely after squeezing out all air from the inside.
Put the bag flat on a hard surface like kitchen counter. Starting from the bottom of the bag, roll a rolling pin over the bag upwards and back.
Repeat untill the shells crack.
Take out the nuts and remove any remaining shells.
