Making your own lilac sugar is a simple and elegant way to capture the flavor and scent of fresh lilacs during the height of the season. Use it to sweeten cakes and muffins, lemonade, or tea, or label your lilac-infused sugar in a pretty little jar for a great gift.

Lilac season is brief. If you’re not intentional, you’ll miss it. I loved the floral aroma and flavors in my recent lilac simple syrup so much that I was determined to use these fresh flowers to the fullest.
Lilac sugar is a simple recipe where you alternate layers of sugar and flowers, then let them infuse.
When it’s ready, you’ll have cups of lilac sugar on hand to sweeten your bakes or hot drinks. Lilac recipes are elegant and luxurious, and the perfect way to incorporate the loveliness of spring.
Note: While the common lilac has edible purple flowers, the Persian lilac is commonplace in landscaping and toxic if ingested. Determine the species before consuming the plant.

How to Make Lilac Sugar
Step 1: Gather the lilac blossoms, choosing those that look healthiest. Remove all green stems or leaves. Give the flowers a good shake or rinse them in cool water to remove any bugs or debris. Let air dry completely.
Step 2: Add a layer of sugar to the bottom of a clean jar, followed by a layer of dried lilacs. Repeat these layers until the jar is full, with sugar as the last layer. Cover with an airtight lid. Store the jar in a cool, dark place for up to seven days, shaking the contents to prevent clumping.
Step 4: After several days of infusing, pour the sugar onto a plate and let it dry out. Once dry, you can choose to remove the individual blossoms or leave them in the sugar. Store in a dark, cool place.
Tips
- Use the freshest blossoms you can find for the most flavor, and remove all of the green parts as they can be bitter.
- After rinsing the flowers, let them air-dry for several hours until completely dry. If they are not completely dry, they could make the sugar clump and possibly mold.
- Make sure to use the common lilac flower as there are certain varieties that are not edible.
