This grapefruit soda, made with a naturally sweetened simple syrup, is a great anytime drink. Add a splash of booze and you’ve got a quick, low-sugar cocktail!

1 cup fresh ruby red grapefruit juice
½ cup honey
1 tablespoon fresh lemon juice
2 sprigs fresh rosemary
Bring zest, grapefruit juice, honey, lemon juice and rosemary sprigs to a boil over medium-high heat in a small saucepan. Remove from heat and let mixture steep for 1 hour before straining through a fine mesh sieve.
Store grapefruit-honey syrup in an airtight glass container in the refrigerator until ready to use.
