My mother in laws wonderful Ranch Dressing! Please go by original recipe and if it is too thick for you, add a little buttermilk. I modified it to my taste and you can do the same. 1 Cup Mayonnaise 1 Cup Buttermilk 1/4 "heaping" t Garlic Powder 1/2 "heaping" t Onion Powder 1/4-1/2 Salt (Start with 1/4 taste and add more if needed) Black Pepper to taste ( I add 1/2t cracked) Parsley (recipe doesn't say but I add 2 Tbsp)
