I've seen several requests regarding Roka Blue, so for those of you lovers looking for this discontinued product you're in luck, because I found it. Kraft Kitchen themselves swear this is the perfect substitute recipe for the original! This recipe equals two of the original 5 ounce jars.
8 oz. cream cheese, softened
1/4 cup blue cheese, crumbled
water for thinning, if desired
Mix the cream cheese and blue cheese until well blended; add 1 tablespoon at a time of water (up to 5 tablespoons) for a thinner consistency if desired.
Note: For a tangier flavor add 1/2 teaspoon white vinegar.
