Crush the garlic. 

In a large bowl, add the tahini, water, lemon juice, garlic, and salt.

Use a whisk or a fork to whisk the tahini until it emulsifies and turns into a paste.

Taste and fix seasoning. If the paste is too thick, add a small amount of water and whisk the tahini again. The tahini’s consistency should be smooth, not gritty, and pourable. 

You can garnish the tahini with chopped parsley. serve it with fresh pita bread.
