I've got this recipe from the site of David Lebovitz, all credits for him and his won-der-ful blog. Truly one of my favorites. You also have to read his article The Hummus Factory. Here is the link.

Adapted from the Cabbagetown Café Cookbook (Crossing Press) by Julie Jordan

3 large cloves of garlic, coarsely chopped
1 teaspoon coarse salt
3/4 cup (180g) tahini (sesame paste)
2 tablespoons olive oil
1/3 cup (80ml) freshly-squeezed lemon juice
2 cups (350g) drained canned chickpeas, (reserve the liquid)
1 cup (15g) gently-packed parsley leaves, preferably flat-leaf
1/8 teaspoon chile powder
6 tablespoons (or more) of chickpea liquid

1. In a blender, whiz together the garlic, salt, tahini, olive oil, and lemon juice until the garlic is finely-chopped.
2. Add the chick peas, parsley leaves, chile powder, and 6 tablespoons of chick pea liquid, and pulse until smooth. Stop the machine a couple of times during blending to scrape down the sides to make sure everything gets well-incorporated.
3. Taste, and add more lemon juice or salt if desired, and more of the chick pea liquid until it reaches a thick, but spreadable consistency. You can make it as smooth, or as coarse, as you want. I like mine mid-way between the two.

Serving: I make a well in the center and drip in some good olive oil and cracker pepper in the crater. Serve with toasted pita chips, baguette slices, or whole wheat crackers. Sometimes I’ll add a generous sprinkle of chopped chives or scallions along with the parsley to my hummus as well. It’s also good with raw vegetables, as a dip.

Storage: Hummus will keep in the refrigerator for up to four days. You can also freeze hummus, well-wrapped, for up to two months.

Note to self: try with canned artichokes instead of chickpeas!
