My family loves Ranch dressing. I always buy it because I never remember to have the ingredients on hand to make it. I finally just made some yesterday and it was great.
1 cup mayonnaise
1 cup of buttermilk
1/2 t salt- I put too much salt in mine, beware, you can always add salt later
1/2 t pepper
1 t dill weed
1 t garlic powder
1 t fresh or dried parsley (I used fresh)
sprinkle of Italian seasoning
sprinkle of paprika
Put all ingredients in glass jar. Put lid on tightly and shake. I ended up have to get a fork and stir it to work out the mayo lumps. You could also use onion powder or whatever herbs you like. This is just what I had on hand. Tasted just like the bottle stuff, but was fresh and I knew what was in it. I have enough dressing to last a month!
