Boil 2 cups of water and 3 tablespoons of baking soda. Add 1 cup of hazel nuts and boil for 3 minutes. Drain nuts in a colander and run cold water over nuts to cool. Squeeze the nuts to pop off the skins and place husked nuts on a kitchen towel to drain. After the nuts are all husked, roast in a 350 degree oven for 12-15 minutes, remove, salt and enjoy.
