Important Note about Salt: Not all salts are made equal and cannot be substituted 1:1. If you are substituting table salt for kosher salt, you will need to cut the amount called for in the recipe by at least half.
Do not use an electric tool like a handheld mixer, immersion blender, or a stand blender or food processor. The heavy mixing turns them into gooey and gummy mashed potatoes. Not exactly the texture we're going for!
