Chickpea Coffee Substitute Recipe
Garbanzo beans — plain chickpeas — also make a satisfactory coffee-like drink, according to Irene Potter of Neosho, Missouri. All you have to do, Irene says, is  roast some chickpeas in a 300 degree oven until they're "the color of roasted coffee beans", then  grind the brown-black nuggets, (in a blender, coffee grinder or Corona-type mill) to the consistency of canned percolator-type coffee. ("Bigger chunks are better than a very fine grind," Ms. Potter advises. "They leave less residue in the pot.")
To prepare a pot of "chickpea coffee", simply measure the ground chickpeas the same as you would regular Java, perk them in a percolator until the liquid looks like fresh-brewed coffee, pour, and enjoy. If you don't have a percolator, just boil the chickpea granules in water. (Be sure, though, to let the boiled pot stand for a few minutes before pouring — or else use a tea strainer — to keep "sludge" from finding its way to the bottom of your cup.)
