Lavender-Blueberry Syrup (makes about 1 cup)

Fresh blueberries
Granulated sugar
Water
Dried culinary lavender buds
Fresh lemon juice

For Each Fizz (recipe yields 2 drinks)

Lavender-blueberry syrup (above)
Vodka (or gin) — omit for a mocktail
Fresh lime juice
Chilled club soda or sparkling water
Ice cubes
Fresh blueberries and a lavender sprig, for garnish

Directions

Prepare the syrup. Combine blueberries, sugar, and water in a small saucepan over medium heat. Lightly mash the berries, bring to a gentle simmer, and cook for 5 minutes. Remove from the heat, stir in the lavender, cover, and let steep 10 minutes. Strain, then stir in lemon juice. Cool completely and refrigerate.
Build the drink. Fill a highball glass with ice. Add 2 tablespoons syrup, 2 ounces vodka (if using), and 1 ounce lime juice; stir gently.
Finish. Top with 4–6 ounces chilled club soda, give one brief stir, and garnish with blueberries and a lavender sprig. Serve immediately.

Servings and Timing

Yield: 2 drinks
Prep Time: 5 minutes
Cook Time (syrup): 10 minutes
Total Time: 15 minutes

Variations

Mixed-Berry Fizz: Replace half the blueberries with raspberries or blackberries for a more complex berry profile.
Herbal Twist: Substitute half the lavender with fresh rosemary or thyme for earthier notes.
Citrus Swap: Use grapefruit or orange juice in place of lime for a softer, sweeter acidity.
Spirit Options: Gin highlights the floral tones; white rum lends subtle tropical sweetness.
Sparkling Wine Upgrade: Top with dry prosecco instead of club soda for a festive cocktail.

Storage/Reheating

Syrup: Store in a sterilised jar in the refrigerator for up to 1 week. Shake before each use; reheating is unnecessary and can dull the floral aroma.
Finished Drink: Best enjoyed fresh. Once topped with soda, the fizz loses carbonation after about 20 minutes.
Freezing Option: Pour leftover syrup into an ice-cube tray; freeze for up to 2 months and thaw cubes as needed for single-serve drinks.

FAQs

Can I make the syrup with frozen blueberries?

Yes. Frozen berries release juice quickly and work just as well; no changes to quantities or timing are required.

What type of lavender should I buy?

Use food-grade dried culinary lavender buds. Decorative or potpourri lavender may contain oils or additives unsuitable for consumption.

Is there an alcohol-free version?

Absolutely—omit the vodka and increase club soda to taste for a refreshing mocktail.

Can I substitute the vodka with another spirit?

Gin complements the botanical notes beautifully, while white rum adds gentle sweetness. Adjust to your preference.

How sweet is the finished drink?

It is lightly sweet. Add an extra teaspoon of syrup for a dessert-style cocktail or reduce it for a drier finish.

Why is lemon juice added to the syrup?

A small amount of acid brightens the blueberry flavour, balances sweetness, and helps the syrup maintain its vivid colour.

Can I carbonate the entire batch in a soda siphon?

Not recommended; blueberry pulp can clog the siphon valve. Carbonate plain water instead, then mix per glass.

Will fresh lavender work instead of dried?

Yes—use double the quantity (fresh blossoms are less concentrated) and steep for the same time. Strain thoroughly.

How long will the syrup keep?

Stored cold in a sealed jar, it tastes best for about seven days; afterwards the floral notes gradually fade.

Can I scale the recipe for a party punch?

Prepare the syrup ahead, combine it with the chosen spirit in a pitcher, and store chilled. Add ice and top with soda just before serving to retain effervescence.
