Lilac Syrup
Making a simple syrup of lilacs, water and sugar will make your summer drinks have that little 'something' that no other drink will. Lilac syrup tastes just like it sounds. A syrup that tastes like the fragrance of lilacs. It is that simple!
Lilac syrup ingredients
- 2 cups water
- 2 cups sugar
- 1 cup lilac flowers
- 4 blackberries, fresh or frozen
Preparing lilacs for simple syrup
- Make sure the lilacs were not treated with pesticides or sprays.
- Harvest the lilacs first thing in the morning while the temperatures are cooler and the blossoms are at peak moisture content.
- Shake off any dead blossoms.
- Remove just the blossom, leaving behind the stems, leaves and the green bits.
- Don’t freak out if you have bits of green.
Lilac syrup instructions:
- Combine the water, sugar, lilac flowers and blackberries.
- Bring to a boil and completely dissolve the sugar.
- Turn off the heat and allow to steep and cool completely.
- Strain the syrup, removing the flowers and the blackberries.
- Store in a closed container in the refrigerator for up to 10 days.
Lilac color in the simple syrup
The natural color of lilacs, when boiled is a pale yellow. But with the addition of a few black berries, fresh or frozen, the lovely lilac color to the syrup. If you don't have black berries on hand, a drop or two of food coloring will work as well but I was going very all natural for this recipe. The lilac syrup is just as good if you don't add any color. But when we eat and drink with our eyes first, I add the purple color to the syrup to call it out as lilac syrup.

I tried to double the recipe, but my math was poor. I added 2x the lilac called for, but not the simple syrup. It's excellent, and I want to make that mistake again! Thank you!

I tried the recipe, and it was great. I needed a smaller amount of the syrup so I just split the amount of every intrigent in half. Since I don't drink alcohol I put it in my lemonade, the syrup gave it an interesting flowery taste, overall a great recipe.
