Important Note about Salt: Not all salts are made equal and cannot be substituted 1:1. If you are substituting table salt for kosher salt, you will need to cut the amount called for in the recipe by at least half.
If your tahini sauce is too bitter, balance it with more lemon juice and 1-2 teaspoons of maple syrup. Tahini can sometimes taste bitter from the type of sesame seeds used, their roasting level, or the presence of the seed's outer hull during processing.
