Whisk together. Add the tahini, water, lemon juice, garlic, salt, and cumin to a mixing bowl. Then whisk together until it's creamy. It may look a bit separated at first, but keep whisking until it's creamy. Alternatively, you could add all of the ingredients to a food processor and blend together.
Taste it. Taste the tahini sauce and adjust any flavors as desired to your liking, before serving.
