Cucumber Cardamom Lemonade

2 oz cucumber juice (see note)
1.75 oz fresh lemon juice
1 oz rich simple syrup
2 oz water
1 tsp Cardamom extract
Optional: 1 oz gin or vodka

Add all ingredients to a cocktail shaker over ice and shake for 20 seconds. Strain into a tall ice-filled glass and garnish with a cucumber slice or lemon twist.

Note: A 4 - 5 oz slice of cucumber will yield 2 oz juice. If you don’t have a juicer, grate the cucumber into a sieve over a pitcher and press to extract the juice.
