To make Arabic coffee, first grind Arabic spices with a mortar and a pestle. Next, add the spices and the coffee to a single serving sized can. Pour water into the can and add a bit of granulated sugar. Stir the coffee, the spices, the sugar and the water together. Place the can over a flame and heat the coffee until it almost boils over. Spoon the foamy coffee mixture into a cup. Once the foam is gone from the coffee can, heat the remaining coffee again until it almost boils over. Pour the purified Arabic coffee into cups and enjoy.
