Homemade Ranch Dressing

I adapted this from Chef John's recipe - I changed the ratios of sour cream, buttermilk and mayo. I changed everything except the main ingredients, lol

1/4 cup (2 parts) sour cream

1/4 cup (2 parts) buttermilk or milk with a splash of vinegar

1/4 cup + 2 tbsp (3 parts) of mayonnaise 

1 tbsp fresh dill

1 tbsp fresh chives (optional)

1/2 tsp garlic powder

1 tsp onion powder

fresh cracked pepper

salt
