How much does potato starch affect a cheese sauce recipe? I'm following this recipe for making cheese sauce:

While purchasing the ingredients I noticed something about pre-shredded cheese versus a block (Kraft brands); they are exactly the same via the Ingredients list on the package except the pre-shredded cheese has added an unspecified amount of potato starch.

Will this affect the amount of flour (or other ingredients) required or even make the product not come out as intended?
Hmm I suppose they add starch to keep it from turning back into one block of cheese.

Thing to do is if the sauce looks to thick just add more milk.
