Lilac Simple Syrup Recipe

Spring in California means my lilacs are blooming. I recently picked up a white lilac and decided it was time for me to finally make some fresh lilac syrup for my summer cocktails.

If you’ve ever smelled a blooming lilac bush and wished you could bottle that scent— trust me, this syrup is your answer.

Lilac simple syrup has a delicate floral flavor with a light, slightly citrusy aroma. It’s perfect for spring cocktails, lemonades, or even drizzled over pancakes or yogurt.

Whether you have a white, pink or purple lilac, you can make a syrup. Just triple-check that you have a true lilac that is edible.

Lilac Syrup Tips:

  • The color can range from clear to pale pink or lavender, depending on the lilac variety.
  • You can gently press the blossoms while steeping to draw out more flavor, but avoid mashing them.
  • If you want stronger floral notes, try cold-steeping the flowers in the syrup overnight in the fridge.

How to Use Lilac Syrup:

  • Add to gin or vodka cocktails for a floral touch
  • Stir into lemonade or sparkling water for a garden-inspired mocktail
  • Mix with honey and butter for a floral pancake topping
  • Use in baking glazes or whipped cream for spring desserts

⚠️ Safety Note: Are Lilacs Edible?

Yes! Common lilac (Syringa vulgaris) blossoms are edible and safe for culinary use. Just make sure your flowers:

  • Come from a pesticide-free source
  • Are fully bloomed (buds are more bitter)
  • Are clean and dry before using
  • and you only eat the flower petals, not the rest of the plant

Poisonous Lilacs to Avoid

  • You can NOT eat Persian Lilac (Melia azedarach).
  • Avoid using hybrid varieties unless you’ve confirmed they’re safe and avoid eating leaves, stems, or seeds.

How to make lilac simple syrup

Ingredients:

  • 1 cup water
  • 1 cup sugar
  • 1–2 cups fresh lilac blossoms (purple or white)

Instructions:

  1. Harvest your lilacs and gently rinse them to remove any bugs or debris. Remove the blossoms from the stems (green parts can make the syrup bitter).
  2. In a saucepan, combine water and sugar. Heat over medium until the sugar dissolves completely.
  3. Remove from heat, let the syrup cool for a little bit, and stir in the lilac blossoms. Let steep for 30–60 minutes, tasting as you go. It may take several hours depending on your lilacs though.
  4. Strain out the flowers using a fine mesh sieve or cheesecloth.
  5. Cool completely and store in a glass jar or bottle in the fridge for up to 2 weeks max (freeze it if you have extra you want to use later).
