Using this basic cream sauce here's some inspiration for the American classic dish of Mac & Cheese!
Once you make a basic white sauce, you could add a bit more milk to thin it out because the cheese adds a bit of "gumminess"
Grate in your favourite cheeses. For a mild flavour go with a basic white cheddar.
For more punch go with older aged cheeses or a blend of mild and sharp.
For a gourmet version add the french Gruyere or Comte cheeses or mimolette cheese for it's distinct flavour, mix it with a good melting cheese.
Add feta for a creamy fresh taste.
