⅔ cup tahini
1 tbsp lemon juice (roughly)
⅔ cup warm water (more or less)
pinch of salt
Mix the tahini, lemon juice, warm water and salt. Adjust the salt level to taste and water level for smoothness and thick/thinness.
This is the basic version. Feel free to punch up with garlic, cayenne, paprika, or any other spices you like.
