Crumble blue cheese off the block if using a block.
Combine all ingredients in a bowl and whisk well to incorporate. Press on some of the blue cheese crumbles as you mix to incorporate that flavor throughout the dressing.
Serve right away or store in the refrigerator for later.
Storing Instructions:
Store blue cheese dressing in a glass jar with an air-tight lid, in the refrigerator. Homemade blue cheese dressing should be good for 5-7 days when properly stored.
Make sure to use clean utensil each time you get some dressing out or for best results, pour the some out of the jar instead.
Notes
Changing recipe amount: if you don't need a lot of dressing, feel free to half the recipe ingredients for half the amount of dressing. On the other hand, if you need to make a large amount for a party, feel free to double the recipe.
