Toast the Sesame Seeds: Preheat your oven to 350°F (175°C). Spread the sesame seeds in an even layer on a baking sheet. Toast the seeds for 8 to 10 minutes, stirring occasionally, until they are lightly golden brown. Be careful not to let them burn.
Cool the Seeds: Remove the toasted sesame seeds from the oven and let them cool completely. Let them cool to room temperature before proceeding to the next step.
Blend the Seeds: Transfer the cooled sesame seeds to a food processor or high-speed blender. Process the seeds for about 1-2 minutes, scraping down the sides as needed, until they form a thick, crumbly paste.
Add Oil: With the food processor or blender running, gradually drizzle in the olive oil, starting with 2 tablespoons. Continue processing for another 2 to 3 minutes, or until it becomes smooth.
Tahini Sauce
Mix all the Ingredients: In a bowl, combine the ½ cup tahini paste, 2 tablespoons fresh lemon juice, grated garlic clove, 1 pinch of salt, and ¼ cup water or yogurt. Mix until the sauce is smooth and uniform.
Notes
Store: Transfer the homemade tahini paste or sauce to an airtight container and refrigerate for up to two weeks. Before using, stir until thoroughly mixed.
