Notes
・Pay attention to the freshness of the egg.・If you are worried, stir bowl soaked in hot water.・I made this by comparing several recipes from people born and raised in Rome and from local chefs. This is a recipe based on the Romans. The "process" is different for each person and is not very important. But, the ingredients, such as Pecorino Romano, are important. If you don't follow the rules of ingredients, you'll be ignoring the history and tradition that goes back to Cacio e pepe. They also don't use garlic.・The quantity and ratio of eggs depends on the quality of the eggs in the country.
