He's-Finally-Asleep Nonalcoholic Cooler

I was introduced to the magic of mocktails through Anasuya Basil, and though I haven't yet stocked up on the nutritional powders she recommends, I can attest that just sipping a fruit and vegetable drink improves my wellbeing. Last night, after our lovely baby boy Río finally fell asleep, I concocted this, and it was fabulous! I like mine unsweetened, but you can add maple syrup if you like.

Juice from 8 lemons
Juice from 1 tangerine
1/2 cup cranberry juice
2 cups water
2 Persian cucumbers or 1 English cucumber
mint leaves to taste
maple syrup to taste
cucumber slice for garnish

Blend on high. Serve cold, garnished with cucumber slice. L'Chayim!
