Materials: one pint jar, spoon, milk, mayonnaise, Lawry's Garlic Salt (has to be this brand because of the parsley)
Step One: Get the pint and put the 1 cup of mayonnaise in it.
Step Two: Put milk in it and stir them in together. (Adjust to how thick you want it, it will thicken more in fridge.) You can also use buttermilk.
Step Three: Add 2-3 teaspoons of Lawry's Garlic Salt and stir them in together and put a little cling wrap on top of the pint.
Step Four: Use it or put in the fridge.
This is how to make homemade ranch dressing. It is very good, you should try it.
