Preheat your oven to 400 degrees.  Slice the very top of the head of garlic off, exposing all the individual cloves. Place the garlic on a small square of tin foil and drizzle it with a teaspoon or two of olive oil and then wrap it up and place it on a baking sheet.  Roast at 400 degrees for 35 minutes.  Once it's done unwrap it and pull the cloves of garlic out.  I like to roast a few at a time and then keep them in the fridge to use, or you can freeze them for later use.  If you'd like to use raw garlic in your hummus you can substitute 2-3 large cloves of garlic in place of the entire head of roasted garlic.

Roughly chop the onion and throw it and everything else into a food processor.  Blend till smooth adding a little of the reserved liquid from the can of beans(or your home cooked beans).  Don't be afraid to add liquid as I find it's better when it's got a little bit more because it firms up in the fridge.  Refrigerate 3-4 hours before serving to give the flavors a chance to come out.  Serve any way you like with a pinch of smokey paprika on top(to make it pretty ;)), with fresh veggies, on crackers, in sandwiches, with soft fresh pitas.
