Toast the walnuts. Preheat an oven to 350 degrees F. Arrange walnuts in a single layer on a baking sheet. Bake the walnuts for 8 to 10 minutes. Walnuts can also be toasted over medium-high heat in a pan on the stove top. Toast walnuts in this way for three to five minutes, stirring them occasionally.
Once the nuts are toasted, place them inside a towel, close the towel and rub with your hands to loosen and remove the skins. Pour the walnuts into a strainer to dispose of the skins.
Soak the walnuts in milk overnight. Use enough milk to cover the nuts. The next day, pour the walnuts and milk into a strainer. Remove the walnuts and rub them between your fingers to loosen and remove the skin.
Boil the walnuts in water. Bring a pot of water to a boil. Add the walnuts and boil for two to three minutes. Remove the walnuts with a slotted spoon and transfer to a paper towel. Most of the skin should come off during the boiling.
