This recipe came together from a few different recipes, and from having tried a number of varieties over the years. I generally use dry chickpeas that have been soaked and cooked - of course you could use tinned, which I think gives you about 1 1/2 cups when drained - so if you're using canned just adjust the water accordingly to get the consistency you want. For the garlic, if you don't have any roasted heads ready to go, you could also saute garlic to mellow it out (rather than use raw). I like to throw a few heads of garlic into the oven whenever it's in use for something else - saves using all that energy for just garlic when you need some. (Note...prep time doesn't include cooking the chickpeas or roasting the garlic..).
