Fruits & Berries - A quick way to harvest fruit is to place a plastic sheet under a shrub or tree and shake it. Only ripe fruits will fall onto the sheet.
Leaves - Young leaves and shoots are generally tender and tastier. Older leaves are often tough and bitter.
Nuts & Seeds - To separate shells from nuts and seeds, simply chop up and immerse in water; the shells will float and the seeds will sink.
Removing Bitter Taste - Boil in several changes of water. To leach bitterness out, place leaves or fruits in a canvas bag and submerge in clean stream or river for 1-3 days.
Drying - The key to drying plants is to do so slowly in a dry area away from direct heat and sunlight. Hang plants upside down or place on raised screen and turn over occasionally. Slice or crush tubers and nutmeats to speed up drying process. Fruit may take up to 10 days to dry.
