Place the minced garlic on a cutting board, sprinkle with a pinch of salt, and use the side of a knife to mash and scrape the garlic and salt together for two minutes until it forms a smooth paste.

In a small bowl, whisk together the tahini and lemon juice until smooth. Add the garlic paste, cumin, and a pinch of salt, and whisk to combine.

Gradually add water to the mixture, whisking with the tines of a fork continuously until the dressing reaches the desired consistency. Keep in mind that the dressing will thicken as it sits, so you may need to add more water later on.

Taste the dressing and adjust the seasoning as needed, adding more salt, lemon juice, or water to achieve the desired flavor and consistency.

Serve the tahini sauce immediately with olive oil and parsley to garnish, or refrigerate for up to a week until ready to use.
