1/2 cup tahini paste
1 clove garlic
1/4 - 1/3 cup lemon juice (freshly squeezed)
2-3 heaping tablespoons plain yogurt (optional)
pinch of ground sumac (optional)
salt, to taste
Stir the tahini paste well before measuring it. The oil tends to rise to the top of the container.
Place the tahini paste in a mixing bowl along with the lemon juice, 2 tablespoons yogurt, 1/4 teaspoon salt and mix well.
The mixture will begin to thicken and sieze up. Don't worry!
Grate the garlic into the sauce and add enough warm water to mix it into a smooth paste. Add as much water as you like to achieve your desired consistency. Thick tahini sauce is great if using as a sandwich spread. Thinner tahini sauce is great for drizzling over foods or as a dressing.
When desired consistency is reached, taste for seasoning. Add more lemon juice and/or salt.
Garnish with finely chopped fresh parsley. Sprinkle some sumac over the sauce and serve.
