Drink this in place of plain old water--it's so simple, delicious, healthy and refreshing! I've added fresh lemon verbena along with the cucumber and lemon, as it's so plentiful in my garden right now. But any of the sweet herbs such as lemon balm, mint, or scented geranium leaves (try rose!) would also be wonderful. Or try rosemary, basil, lemon thyme or whatever herb or combination you fancy! I keep a jug of this refreshing beverage in the fridge all summer long. Each batch lasts a day or two--just keep in the fridge, and top off with more bottled water to replenish what you drink. After a couple of days you'll need to make a fresh batch. Enjoy! Recipe is easily doubled or tripled, for events etc.
