1-First Step: Make the citrus base Start by washing the lemons, oranges, and rosemary well. Juice the 2 lemons and 2 oranges, making sure to remove any seeds. Pour the juice into a small saucepan along with the 3/4 cup sugar, 1/4 cup honey, and 4 fresh rosemary sprigs. Set the pan over medium heat and stir gently until the sugar dissolves. This usually takes about 3 to 5 minutes. You do not need to boil it hard. A gentle heat is enough to help the rosemary flavor blend into the sweet citrus mixture.

2-Second Step: Simmer gently Lower the heat and let the mixture simmer for about 5 minutes. This short simmer gives the Rosemary Citrus Spritz Mocktail its herbal backbone without making the rosemary taste too strong. The kitchen will start to smell very fresh and cozy at the same time. If you prefer a stronger rosemary note, let the sprigs sit in the warm mixture for a few extra minutes after turning off the heat. If you want a milder flavor, remove them sooner. That flexibility makes this drink easy to fit different tastes.

3-Third Step: Strain and cool After simmering, remove the saucepan from the heat. Take out the rosemary sprigs and strain the liquid into a heat-safe bowl or pitcher. This gives you a smooth base without any herb bits floating in the drink. Let the mixture cool at room temperature for about 15 to 20 minutes, then place it in the refrigerator if you have extra time. A chilled base will help the final Rosemary Citrus Spritz Mocktail stay colder for longer, especially on hot days.

4-Fourth Step: Build the drink Fill a glass with ice. Add a few tablespoons of the cooled citrus-rosemary base, then top with soda water. Stir gently so the bubbles stay lively. Taste it and add a little more base if you want it sweeter or more intense. This is also the point where you can adjust the drink for different needs. Add more soda water for a lighter drink, or a little extra sweetener if you like a softer citrus edge. The recipe works well in a tall glass, a wine glass, or even a mason jar for a more casual feel.

5-Final Step: Garnish and serve Finish with rosemary and lemon garnish if you want a polished look. A lemon wheel, a twist of lemon peel, or a small rosemary sprig can make the drink look especially pretty. Serve right away while the soda water is still fizzy. For the best result, add the soda water at the very end so your Rosemary Citrus Spritz Mocktail stays bubbly from the first sip to the last.
