In a small mixing bowl, whisk together all ingredients expect the blue cheese until fully combined. Fold in the blue cheese, making sure to leave some pieces in larger chunks for added texture. Taste and adjust seasoning, adding more salt, sugar or acid to balance your particular cheese.
This has a nice garlic kick at the end which I love with the other flavors. If you don't like the lingering taste of raw garlic, replace it with a little minced shallot.
