Use a fork to press blue cheese crumbles into small (but not super fine) crumbs. Set aside.
Soften cream cheese in the microwave for about 20 seconds. It should be soft but not melted.
Combine the soft cream cheese with the sour cream, mayo, sugar and seasonings.
Mix to fully combine.
Add the blue cheese crumbles and fold in.
Add lemon juice and salt and pepper to taste.
The consistency should be a LOT stiffer than pudding, more like spackle, and it will thicken as it chills.
For thinner consistency, add a teaspoon of milk or water and stir if it’s too stiff to comfortably dip a cracker into without breaking.
It’s delicious eaten right away, no chilling needed!
