Lilacs are one of the most wonderful parts of spring. And yet, they are also so very fleeting. Make lilac sugar as a way to save them for the entire year.

This truly is as simple as laying sugar and lilac blossoms in a jar and letting it sit. It’s not a complicated project and yet is so very glorious.

Use Only the Lilac Blossoms

The stems and leaves of lilacs tend to be tough and bitter. Use only the blossoms to make lilac sugar.

Lilac blossoms clipped from their stems sitting a bowl to make lilac sugar.

To do this, simply clip the blossoms from the stems with a pair of scissors. I simply do this standing over a bowl to catch the falling blossoms. Admittedly this takes a little time but it’s not hard or drudgery by any means. Do it outside on the porch and listen to the birds sing for an especially pleasant seasonal activity.

After clipping, do give the blossoms a quick rinse and spin through the salad spinner. This will remove and dirt bugs. Let them sit on a towel for an hour to remove any surface water before proceeding.

Tips for Making Lilac Sugar

Shake the jar of sugar every day for a week. Every day. Skipping this means that the jar of sugar will likely become one solid mass as the sugar pulls the moisture from the lilac blossoms and hardens.

After the blossoms dry (usually 7 days at most), they are essentially preserved, candied. One could strain those bits of flowers from the sugar by pressing it all through a fine mesh sieve

Or one could leave the blossoms in the sugar for a fun bit of color in baked goods.

Perhaps make a jar of each – strained and with flowers. Use the strained sugar for drinks, the flowered sugar for baked goods.

How to Use Lilac Sugar

In short, use lilac sugar anywhere you’d use plain sugar for a light lilac flavor. Simply replace granulated sugar with lilac sugar at a 1:1 ratio in baked goods like cookies or cakes.

Don’t forget to add it to pancakes or waffles for a floral breakfast.

Sprinkle the lilac sugar and bits of sugared and dehydrated lilac blossoms on the tops of cookies or muffins for a floral infused sweet crunch.

Use a little of it to sweeten tea for a floral flavor that is sure to delight.

Make lilac hot cocoa by using lilac sugar instead of plain. Trust me, this is such a delight on a winter night.

Dissolve the sugar in hot water for a simple syrup to flavor cocktails and mocktails.

An Amazing Floral Gift

Sugar lasts a long time. Which means this can easily make for a great gift.

Make a big batch of lilac sugar this spring. Then divide it all into smaller, decorative jars and give it away during the holidays or for birthdays all year long.

My blossoms also turned brown and it smells kind of like coconut oil, not lilac-y. Where did I go wrong?

I can't explain the coconut oil smell at all. However, if it doesn't smell right at all I wouldn't eat it. Sugar is a pretty amazing preservative so nothing should spoil but be safe.

The blossoms do often turn burnish, they just give up their color but it's not bad per say.

I have done this 3 days ago.y flowers are brown and have a pungent kind of smell (they are starting to ferment I think). They are also brown :( did I do something wrong?

I've never had them ferment, the flowers do lose color.

Are the blossoms supposed to stay purple? I have tried three times now and they turn brown within 12 hours (not very pretty). The third time I tried laying the blossoms on a sheet tray and putting the sugar over the top so it wasn't so wet. Then I forgot I had set it in the oven and went to make bread and by the time I realized what I had done the oven was preheated. My sugar now smells like soap. I hate to throw it out though. I think I should try a different way to use lilacs lol. I make jelly and love that though.

They will definitely lose color in the sugar. Even when I bake with them in cookies, etc. they lose color.
