It may be simply that when the heated starch granules soak in liquid and swell, they become large enough to physically keep proteins apart. Whatever the science, we know from experience that starches —flour, cornstarch, potato starch, tapioca—can keep cheese sauces smooth and allow us to heat them without worry.

A second problem when cooking with cheese is that it can get stringy when stirred into sauces or soups. Norman Olson of the University of Wisconsin explains that some cheese, particularly Swiss and mozzarella, contain calcium phosphate, a compound that tends to link cheese proteins together to form long strings.

Even when heated gently, the stringy character of these cheeses makes them unmanageable and almost impossible to stir or serve. This can be prevented by adding a bit of wine or lemon juice to the cheese before melting it. Traditional cheese fondue recipes contain white wine to prevent stringiness. Anthony Blake, director of food science and technology for an international flavor and fragrance company, explains that the tartaric acid in wine helps prevent the calcium phosphate from linking cheese proteins together, thus preventing stringiness; he adds, however, that the citric acid in lemon juice is much more effective.

Citric acid actually binds with calcium and can overcome stringiness even in the extreme case of mozzarella. I now make fettuccine with a mozzarella, prosciutto, mushroom, and tomato sauce that I love.
