Blue Cheese Dressing

I am a latecomer to loving blue cheese dressing. It is most delicious. I've of course modified a recipe I found online.  Here are my ingredients:

• 1 cup Greek yogurt
• 1/2 cup mayonnaise 
• 1/4-1/2 cup of milk based on preferred thickness
• 1 teaspoon red wine vinegar 
• 1 teaspoon white vinegar
• 1 teaspoon lemon juice
• 1 clove garlic, minced (optional)
• 8 oz crumbled blue cheese
• 1/8 teaspoon kosher salt
• 1/2 teaspoon fresh ground black pepper

 Mix all but milk together. Add milk a bit at a time to get desired thickness. Store in mason jar for up to a week.
