Stove Top Method
Get shelled walnuts and split them into halves. Take a skillet of required size, and place it on medium heat. Heat the walnuts till they release a nutty aroma, and turn golden brown in color. Don't forget to stir them constantly, so as to prevent burning of the nuts, which are at the bottom of the skillet. Once done, remove the skillet from the stove, and let the walnuts cool before use. This method is the best, if you want to toast a small amount of walnuts.
