Tahini Sauce with Yogurt

This is a wonderful sauce which can be used on roasted vegies, such as eggplants, or fish.  It is a great starter for humus - make this and then add your beans and pulse until smooth!
1 clove garlic
1/3 cup tahini
1/3 cup Greek yogurt
juice of 1 lemon or lime
1/4 cup water, additional if needed
1/4 tsp cumin powder
1/4 tsp salt
Dash cayenne pepper to taste

Pulse the garlic in a small food processor until very well minced. Add remaining sauce ingredients and blend well. Adjust consistency with more water if necessary, and adjust seasoning with salt and cayenne pepper.

Makes about 1-1/4 cup sauce.
