Walk into any American supermarket and you will find bottles labeled 'Italian Dressing.' They contain garlic powder, dried oregano, sugar, xanthan gum, and a list of ingredients no Italian grandmother would recognize. This is not Italian. This is a commercial product invented for people who have never eaten in Italy.

The true Italian dressing is citronette: fresh lemon juice, good olive oil, salt. That is all. Some variations exist. A drop of Dijon mustard helps the emulsion hold. A minced shallot adds sweetness. But the foundation remains three ingredients, and what you keep out is as significant as what you put in.

Simple does not mean careless. The lemon must be fresh, squeezed moments before use. The olive oil must be extra virgin, with character and fruit. The salt must dissolve completely. When these three elements are in proper balance, you understand why Italian cooks have dressed their salads this way for centuries. They were not missing anything. They had already found perfection.
