In addition you must have a large (at least 5 pints) lidded container with a wide mouth. Begin by blanching the walnuts and pistachios. Bring 3 cups of water to a boil, remove from the heat, add the walnuts and pistachios, cover and let it sit for 20 minutes. In the meantime in a large bowl add both kinds of raisins, cherries and apricots. Rinse three times in cold water to remove any residue.
