This is another recipe from my aunt which I LOVE. It seriously tastes like the string cheese out of a can, without the weird visual.
2 jars Kraft Old English (can be found in the cheese section at your grocery store, it is glass)
1 jar Kraft Roka Blue (same as above)
1 8oz. package cream cheese softened
Blend together with a hand mixer (or I am sure a Kitchen Aid would work if you have one). After placing everything in the bowl, I usually let it sit for awhile to get really softened so it is easier to mix, other wise, it stays all clumpy rather than getting nice and smooth.
Serve with crackers. I like this with traditional Keebler Club Crackers or those Stix for dipping!
