Here's my blue cheese dressing recipe:
1/3 cup blue cheese crumbled
1/3 cup sour cream
1/2 cup mayonnaise
2 tbsp of strained lemon juice (or more to taste and depending on thickness of dressing)
1/4 tsp fresh thyme (leaves only)
1/4 tsp fresh chives, finely chopped
black pepper (to taste, but at least 5 good grinds of pepper)
white pepper (to taste)
salt (to taste)
optional: pinch of sugar or some honey (to taste if you like your dressing on the milder side)
1/4 cup blue cheese crumbles
Blend all of the listed ingredients except for the 1/4 cup of blue cheese crumbles in a blender. If it's too thick, but already has enough acidity or tanginess, add water or a little bit of milk. Re-blend.
Finish by folding in the remaining blue cheese crumbles. It's best to chill it for a few hours before using so it gets nice and thick.
It's great as a dressing, but also with Buffalo wings. I've tried this with Danish Blue, Point Reyes Blue and a few other blue cheeses and it works well with all. The saltiness of the cheese is one big variable; as I recall, Maytag is not very salty so you will probably want to add some salt. With others, like the Point Reyes Blue I just used this week, no salt was added; the cheese was salty enough on its own.
You can also substitute your favorite herbs like italian parsley, green onions. You can also add shallots, onions or a little garlic.
