Step-by-Step Instructions
Step 1: Crush the juniper and peel the citrus
Place 1 1/2 tablespoons dried culinary juniper berries on a cutting board and gently press them with the bottom of a small skillet, the flat side of a chef’s knife, or a muddler. You want the berries cracked open so they release their aroma, not ground into a powder. Use only juniper berries labeled for culinary use.
Before juicing the fruit, remove 3 wide strips of orange peel and 2 wide strips of lemon peel with a vegetable peeler. Try to take mostly the colorful outer zest and as little white pith as possible, because the pith can make the syrup bitter.
Step 2: Make the juniper citrus syrup
In a small saucepan, combine the crushed juniper berries, 6 tablespoons granulated sugar, 6 tablespoons filtered water, the orange peel, the lemon peel, and 1/16 teaspoon fine sea salt. Set the pan over medium heat and stir until the sugar dissolves, about 3 to 4 minutes.
Bring the mixture to a gentle simmer, about 190 to 200°F. Once it is lightly bubbling around the edges, reduce the heat to low and simmer for 1 minute. Avoid a hard boil, which can pull too much bitterness from the citrus peel and make the juniper taste sharp.
Step 3: Steep and strain the syrup
Remove the saucepan from the heat, cover it, and let the syrup steep for exactly 15 minutes. This gives the drink its delicate botanical flavor while keeping the juniper smooth and balanced.
Strain the syrup through a fine-mesh sieve into a heatproof liquid measuring cup. Do not press hard on the solids; a gentle drain keeps the flavor clean. You should have about 1/2 cup syrup. Discard the strained juniper berries and citrus peels.
Step 4: Cool the syrup and prepare the juices
For fast cooling, set the measuring cup of strained syrup in a small bowl filled with ice water for 5 minutes, stirring once or twice, until the syrup is about room temperature, approximately 70°F. If you are not in a hurry, refrigerate it uncovered for 20 minutes, then cover once chilled.
While the syrup cools, juice the oranges and lemons. You need 1/2 cup fresh orange juice and 1/4 cup fresh lemon juice. Strain the juices if you prefer a clearer drink, or leave a little pulp for a more homemade texture. Keep the juices cold until you build the drinks.
Step 5: Build the citrus base in each glass
Set out four 12-ounce highball glasses. Add 1/2 cup ice to each glass. Pour 2 tablespoons juniper citrus syrup, 2 tablespoons fresh orange juice, and 1 tablespoon fresh lemon juice into each glass. Stir for about 5 seconds to combine the syrup with the citrus before adding the sparkling water.
Step 6: Add sparkling water gently
Slowly pour 6 fluid ounces of chilled plain sparkling water into each glass. Pouring down the inside of the glass helps preserve the bubbles. Stir each drink once or twice with a long spoon, just enough to blend without flattening the sparkle.
Taste one drink before garnishing. For a sweeter cooler, add 1 teaspoon extra syrup per glass. For a brighter, more tart cooler, add 1 teaspoon extra lemon juice per glass. For a lighter drink, add 1 to 2 extra ounces sparkling water per glass.
Step 7: Garnish and serve immediately
Garnish each cooler with 1 orange wheel, 1 lemon twist or lemon half-moon, and a few culinary juniper berries. The garnish berries add aroma and visual charm, but they are quite strong when chewed, so they are best treated as a garnish rather than a snack.
Serve the Juniper Berry Citrus Coolers right away while the ice is fresh, the citrus is bright, and the sparkling water is lively.
Pro Tips
- Use culinary-grade juniper berries: Buy dried juniper berries from a spice shop or grocery spice aisle. Do not use berries from ornamental landscape plants.
- Crack, do not grind: Lightly crushed berries give a clean botanical flavor. Finely ground juniper can make the syrup cloudy and more resinous.
- Keep the citrus peel pith-free: The colorful zest adds fragrance; the white pith adds bitterness. A vegetable peeler works better than a knife for this job.
- Chill everything: Cold syrup, cold juice, cold glasses, and sparkling water at 38 to 40°F make the drink taste crisper and keep the bubbles lively.
- Add bubbles last: Mix the syrup and juices first, then top with sparkling water right before serving so the drink stays effervescent.
Variations
- Grapefruit Juniper Cooler: Replace 1/4 cup of the orange juice with 1/4 cup fresh pink grapefruit juice for a lightly bitter, rosy version.
- Herbal Garden Cooler: Add 4 fresh basil leaves or 1 small rosemary sprig to the hot syrup during the final 5 minutes of steeping, then strain with the juniper and citrus peel.
- Lower-Sugar Cooler: Make the syrup with 4 tablespoons sugar and 6 tablespoons water instead of 6 tablespoons sugar and 6 tablespoons water. Use 1 1/2 tablespoons syrup per glass and add an extra 1 tablespoon orange juice if desired.
Storage & Make-Ahead
The strained juniper citrus syrup can be made up to 10 days ahead and stored in an airtight jar in the refrigerator at 40°F or colder. For longer storage, freeze the syrup in 1-tablespoon portions for up to 2 months, then thaw only what you need. Fresh orange and lemon juices are best within 24 hours, stored covered in the refrigerator. Do not combine the syrup, citrus juices, and sparkling water until just before serving, because the sparkling water will lose its fizz. You can slice the orange wheels and prepare the lemon twists up to 4 hours ahead; keep them covered and refrigerated until serving.
