Take your measured out ingredients and prepare to put them in your mixer.
Begin by placing your sour cream, mayo, horseradish, green onions and lemon juice in mixing bowl. Salt and pepper to taste.
With a whisk attachment, Whisk at medium to high speed for about a minute or until nicely mixed. (If you do not have a mixer, this can be done by hand. With a bowl and whisk)
Place in container, add cracked pepper & garnish with green onion and place in refrigerator until ready to serve. ENJOY!
