This crisp and refreshing spritzer gets its garden-fresh flavor from juiced cucumbers and fennel. If desired, add limoncello (a lemon liqeuer) for a great cocktail.
Juice cucumbers and fennel in an electric juicer. (You should have about 3 cups liquid.) Transfer to a large pitcher. Stir in club soda, honey, lemon juice, salt and limoncello, if desired. Serve over ice. Garnish with lemon-peel strips and fennel fronds.
