Pretty much any kind of cheese can be used to make a cheese sauce to accompany pasta and vegetable dishes, one of the most famous being Bechamel. Ingredients typically used are flour, milk, butter, eggs and spices like nutmeg and pepper. Cheese in sauces sometimes curdles if cooked over too high a temperature, particularly if mixed with eggs. This doesn't necessarily mean you have to discard it, as there are a few things you can do to uncurdle it, however note these methods might not work if the cheese is extremely curdled.

Remove the mixture from the heat and stir very vigorously until the cheese curds have dissolved into the sauce.
Step 3

Step 4
Remove from the heat and add a little cornflour and water to thicken the sauce you're making with the cheese. While this thicker sauce won't uncurdle the cheese, it will help to hide some of the curdles.
