To make lavender simple syrup, combine 1 cup water, 1 cup sugar, and 2 tablespoons dried culinary lavender in a saucepan. Heat over medium until sugar dissolves, then simmer for 5 minutes. Strain and cool. Store in a sealed container in the refrigerator for up to 6 weeks.

What Is Lavender Simple Syrup?

Lavender simple syrup is a flavored liquid sweetener made by infusing sugar and water with culinary-grade lavender blossoms. It's commonly used in cocktails, lemonades, iced teas, and desserts to add a floral, aromatic sweetness. The syrup balances the natural bitterness of lavender while enhancing its delicate perfume.

Why Use Lavender in Syrups?

Imparts a unique floral flavor ideal for gourmet beverages
Natural calming properties associated with aromatherapy
Enhances both alcoholic and non-alcoholic drink profiles
Easy to make at home with minimal ingredients

Ingredients You’ll Need

Using high-quality ingredients ensures a clean, aromatic syrup without soapy or bitter off-notes often caused by incorrect lavender types.

Culinary Lavender vs. Ornamental Lavender

Only use food-safe, pesticide-free Lavandula angustifolia, commonly labeled as “culinary lavender.” Avoid ornamental varieties, which may be treated with chemicals unsuitable for consumption.

Ingredient	Recommended Type	Amount	Purpose
Water	Filtered or distilled	1 cup (240 ml)	Solvent base
Sugar	Granulated white	1 cup (200 g)	Sweetener and preservative
Lavender	Dried culinary buds (L. angustifolia)	2 tbsp (6 g)	Flavor infusion

The ratio of 1:1 sugar to water is standard for simple syrups, ensuring solubility and shelf stability. Dried lavender is preferred due to concentrated flavor and ease of straining. Excess lavender can lead to bitterness, so precise measurement is key.

Step-by-Step Instructions

Follow these steps carefully to extract optimal flavor while avoiding over-extraction that causes soapiness.

1. Combine Ingredients

In a small saucepan, mix 1 cup water, 1 cup sugar, and 2 tablespoons dried culinary lavender. Stir gently to moisten the buds.

2. Heat and Dissolve

Warm over medium heat, stirring occasionally until sugar fully dissolves (about 3–4 minutes). Do not boil vigorously—gentle heat preserves volatile oils.

3. Simmer and Infuse

Reduce heat to low and simmer for exactly 5 minutes. This duration maximizes flavor extraction without releasing harsh tannins.

4. Cool and Strain

Remove from heat and let steep for another 10–15 minutes. Strain through a fine-mesh sieve or cheesecloth into a clean bottle or jar.

5. Store Properly

Cool completely before sealing. Refrigerate in a sterilized glass container. Lasts up to 6 weeks.

Tips for Best Results

Always use fresh, food-grade lavender—stale buds yield weak flavor
Label your syrup with date and contents
Add a splash of vodka (½ tsp per cup) to extend shelf life if needed
Avoid aluminum pans, which can react with floral compounds
For richer syrup, use a 2:1 sugar-to-water ratio (gommage style)

Creative Uses for Lavender Simple Syrup

This versatile syrup elevates both drinks and dishes:

Cocktails: Add to gin & tonics, mojitos, or champagne spritzers

Frequently Asked Questions About Lavender Simple Syrup

Can I use fresh lavender instead of dried?

Yes, but use triple the amount (about 6 tablespoons) since fresh buds have higher water content. Be cautious—fresh lavender can impart stronger, sometimes bitter notes. Lightly bruise the buds before adding to enhance infusion.

Why does my lavender syrup taste soapy?

Soapy flavors occur when too much lavender is used or it’s steeped too long. Stick to 2 tablespoons dried per cup and limit simmer time to 5 minutes. Also, ensure you’re using Lavandula angustifolia, not hybrid ornamental types high in camphor.

How long does homemade lavender syrup last?

When stored in a clean, airtight container in the refrigerator, it lasts up to 6 weeks. For longer storage (up to 6 months), freeze in ice cube trays and thaw as needed.

Is lavender simple syrup safe for children and pregnant women?

In culinary amounts, yes. However, therapeutic doses of lavender are not recommended during pregnancy. Always consult a healthcare provider if unsure. Use moderation, especially with young children.

Can I substitute honey or other sweeteners?

You can replace sugar with honey or agave, but this changes flavor and preservation. Honey introduces additional botanical notes and may reduce shelf life. These alternatives also affect texture and clarity. For best results, start with granulated sugar.
