Physicists have discovered the key to a consistently delicious pasta cacio e pepe, a traditional Italian dish made with black pepper and pecorino cheese.
Making cacio e pepe involves melting the cheese with the water in which the pasta is cooked to create a smooth sauce, but this is very difficult to achieve. If the mixture becomes too hot or has the wrong balance of pasta water cheese and starch, the sauce will become unpleasant rather than smooth.
