Blue Cheese Dressing

I wanted to blog this just in case I lost the recipe. It was great on a salad, but I suppose would also be great with buffalo wings. In any case.....

1 Tbsp hot bacon fat (I omitted this for R)
1/2 c sour cream
3 Tbsp whole milk
2 Tbsp cider vinegar
1/4 tsp salt
1/4 tsp fresh ground pepper
1 scallion, chopped
2/3 c crumbled blue cheese

Whisk bacon fat, sour cream, milk, vinegar, salt, and pepper until smooth. Stir in the scallion and the blue cheese. Thin with additional milk if desired.
