i usually put like one lemon, four or five tbs. of maple syrup and about 2 1/2 cups of purified water in a blender at a time. i add the cayanne as i go, but the way i do it makes about 3 cups of lemonade at a time. it works well for me because i end up making it twice a day and it stays really fresh. if my boyfriend does do the cleanse when he comes home we'll probably make more at a time and he'd have to add more maple syrup along with the cayanne.
