When making hummus, the amount of salt to be added to the lemon juice and garlic depends on personal preference. Generally speaking, most recipes call for one teaspoon of sea salt or kosher salt to be added to every two tablespoons of lemon juice and two cloves of garlic. However, if you prefer a slightly less salty flavor, you can reduce the amount of salt used. The goal should always be to create a balanced flavor that complements the other ingredients in your dish such as chickpeas and tahini.
