What is the function of salt in quiche?

* Enhances Flavor: Salt is a fundamental seasoning that brings out the natural flavors of the other ingredients, such as the cheese, eggs, and vegetables.

* Balances Sweetness: Salt helps to balance out the potential sweetness of the crust and any sweet ingredients in the filling.

* Improves Texture: Salt helps to strengthen the egg proteins, contributing to a firmer, less watery quiche.

* Improves Browning: Salt can slightly enhance browning of the crust in the oven.

It's important to remember that you should add salt gradually and taste as you go to adjust to your personal preference.
