Start by prepping the jalapeño and garlic. Remove the stems and seeds from the jalapeño, then quarter it to make blending easier.
Use a mortar and pestle to mash the jalapeño and garlic together until they form a soft paste. You can add salt during this step to help break down the ingredients and boost the flavor.
Once the jalapeño and garlic are blended, transfer them to a food processor or blender.
Add the remaining ingredients to the food processor: 2 cups of yogurt and 1/3 cup of tahini paste.
Blend all the ingredients together until you achieve a smooth and creamy texture. This might take a few minutes, depending on your machine's power.
Taste the sauce and adjust the seasoning if needed. Feel free to add more salt or tahini to suit your taste.
Once the sauce reaches your desired consistency and flavor, transfer it to a serving bowl.
You can chill the sauce in the refrigerator for a while to let the flavors blend, or serve it right away. It can be stored in the fridge for up to a week.
Enjoy this creamy yogurt sauce with a kick of jalapeño and tahini as a tasty dip for chips, fresh veggies, or as a flavorful topping for your favorite dishes!
