Peel the garlic cloves and finely mince them, or use a garlic press. If you prefer a milder garlic flavor, smash the cloves and let them sit 5–10 minutes before using, or use 1 clove instead of 2.

Combine tahini and lemon

In a medium mixing bowl, add 1 cup tahini and 1/4 cup fresh lemon juice. Stir vigorously with a whisk or spatula — the mixture will seize and thicken initially. Continue stirring until it lightens slightly in color and smooths out, about 30–45 seconds.

Add garlic, oil, and spices

Add the minced garlic, 2 tablespoons extra-virgin olive oil, 1/2 teaspoon ground cumin, 1 teaspoon salt, and 1/4 teaspoon black pepper to the tahini-lemon mixture. Stir to combine.

Thin to desired consistency

Slowly whisk in 1/2 cup warm water a few tablespoons at a time until the sauce reaches a smooth, pourable consistency. If the sauce is still too thick for your use, whisk in up to an additional 1/4 cup warm water (use the optional warm water ingredient) until desired thickness is achieved. Taste and adjust seasoning: add more salt, lemon, or water as needed.

Rest and meld flavors

Let the sauce rest at room temperature for at least 10–15 minutes so the garlic and lemon flavors meld with the tahini. If making ahead, cover and refrigerate — the sauce may thicken in the fridge; whisk or thin with a little warm water before serving.

Finish and garnish

Transfer to a serving bowl. Drizzle 1 teaspoon olive oil over the top and sprinkle with 2 tablespoons chopped fresh parsley and a pinch (about 1/4 teaspoon) smoked paprika or sumac if using. Serve chilled or at room temperature.
