Peel and discard the papery outer layers of the whole garlic bulb, leaving intact the skins of the individual cloves or garlic.
Using a sharp knife, cut ¼ to ½ in from the top of the cloves, exposing the individual cloves of garlic.
Put garlic in a baking pan or muffin tin, cut side up.
Drizzle with olive oil and make sure the tops of each of the exposed garlic cloves have oil on them.
Cover the bulb with aluminum foil and bake for 30-40 minutes, or until the cloves are lightly browned and feel soft when pressed.
Cool and remove the roasted garlic cloves from their skins by squeezing them out from the bottom and pushing up.
You can eat it as is, spread on toast, mix with pasta, or any number of uses!
Making the Hummus
In a food processor, combine the tahini and lemon juice and process for 1 minute. Scrape the sides of the bowl and then process for 30 seconds more.
Add the olive oil, roasted garlic, cumin, and a ½ teaspoon of salt to the processor.Process for 30 seconds, scrape the bowl down, and then process for another 30 seconds.
Add half the chickpeas to the processor and blend for 1 minute. Scrape the sides and bottom of the bowl. Add the remaining chickpeas and process until thick and smooth (about 1 to 2 minutes).
Add the water to the processor, along with any additional salt (if you feel it needs it).
To serve, put the hummus in a bowl with a swirl of olive oil and a tablespoon of roasted garlic on top.
