In a medium mixing bowl, add ½ cup of tahini and ¼ cup of freshly squeezed lemon juice. Whisk until it forms a thick creamy paste.

Gradually drizzle in ¼ to ½ cup of filtered cold water, whisking until you reach your desired consistency.

Stir in ½ teaspoon of salt and any optional ingredients like minced garlic or herbs, mixing well.

Taste and adjust salt or lemon juice as needed. Let sit for about 5 minutes for flavors to meld.

Transfer sauce into a tightly sealed container for storage; lasts up to 1.5 weeks in the fridge.
