Do you have to add salt in tomato sauce?

Here's why:

* Enhances flavor: Salt brings out the natural sweetness and acidity of tomatoes, making the sauce more complex and delicious.

* Balances flavors: Salt can help to balance out the sweetness of sugar or other added ingredients in your sauce.

* Preserves: Salt acts as a natural preservative, helping to extend the shelf life of your sauce.

However, there are some exceptions:

* If your tomatoes are already very flavorful: If you're using heirloom tomatoes or other varieties that are naturally sweet and salty, you might not need to add additional salt.

* If you're using salty ingredients: If you're adding ingredients like anchovies or salty cured meats to your sauce, you might want to reduce the amount of salt you add.

* If you're watching your sodium intake: If you are on a low-sodium diet, you can certainly omit salt altogether.

Ultimately, the decision of whether or not to add salt to tomato sauce is up to you. It's a matter of personal preference and the specific ingredients you're using.
