I modified this recipe from an Everyday Living recipe. Ranch dressing is a staple in this house, so I like to have it available home made as much as possible, especially since HFCS is in so many of the store bought brands.
1 cup mayonnaise
1/2 cup buttermilk
2 tablespoons lemon juice (and more to taste)
1/2 teaspoon salt
1 teaspoon celery seed
1 teaspoon dried oregano
1/2 teaspoon onion powder
a dash of fresh ground black pepper
1. Combine all ingredients in a medium bowl.
2. Whisk to lighten it up a bit.
3. Serve on salads or as a dip or dressing for sandwiches.
4. Store in an air tight container in the fridge for up to one week.
