Tips

  • It is important to slice the onions uniformly and thinly (about 1/4 inch thick) so that they melt and are silky, not crunchy.
  • You can use either light or dark brown sugar.
  • You can use sharp cheddar cheese if you prefer.
  • You can use Parmesan Reggiano or Grana Padano instead of Pecorino Romano cheese.
