30+ Lilac Recipes (Yes, Lilacs Are Edible!)

Edible lilacs (Syringa vulgaris) are one of the most delightful surprises of the spring kitchen, and yes, you really can eat them. Between the fragrant flowers and the short bloom window, lilacs have become one of my favorite things to preserve and cook with each May on our Vermont homestead.

Every year I wait for the sweet smell of lilacs to announce the arrival of real spring. While they only bloom for a few short weeks, their intoxicating scent fills the air and lifts my spirits after a long Vermont winter, and I’d plant them just for their beauty.

But lilacs have one more gift to offer: they have edible flowers, and they turn into some of the most beautiful preserves, drinks, and desserts too!

Lilacs are on just about every old Vermont homestead, and you can even find them growing wild in the woods, marking spots where a stone foundation once supported a house. The lilacs have outlived both the gardener and the building, and they still smell sweet with no one around but the bees.

Lilacs start the edible flower season around here, but our homestead has delicious blooms to enjoy all summer long. We’re foraging dandelions for dandelion flower recipes at the same time as the lilacs, then wild violets come on for violet flower recipes, and elderflowers show up a few weeks later for elderflower recipes. The old perennial patch of bee balm by the kitchen door is edible and medicinal too, so the homestead kitchen stays fragrant with one bloom or another from May right through August.

Can You Eat Lilacs?

Yes, common lilac (Syringa vulgaris) flowers are edible. The florets have a delicate floral flavor with a hint of astringency, and they work in jellies, syrups, infused honeys, baked goods, cocktails, and skincare. Purple, white, pink, and lavender varieties are all equally edible, though flavor and color intensity can vary between cultivars.

Only the flowers are used; the leaves, bark, and seed capsules are not part of traditional culinary preparations and are sometimes noted as bitter or mildly toxic.

Of course, it’s always possible to have a reaction to new foods, so start small and make sure they agree with you. Lilacs are part of a broader world of edible flowers that show up on the homestead each spring, right alongside wild violets, dandelion flowers, and eventually roses.

Note that not every plant called “lilac” is the same species, and there is a wild weed known as French lilac (Galega officinalis) that is not edible. It’s a completely different plant, and looks more like sweet peas or vetch than bushy lilacs. They just have a similar name.

How to Harvest Lilacs for Cooking

The best time to harvest lilacs for the kitchen is when most of the individual florets on a spray have opened but before any of them start to brown. Pick in the morning after the dew has dried but before the heat of the day, when the fragrance is strongest.

Snip full sprays with scissors, leaving the developing buds at the base of each branch intact so the shrub will continue blooming.

Once you’re back in the kitchen, the fiddly part begins: stripping individual florets from the woody stems AND pinching off the small green flower bases at the bottom of each floret. Those green bases (the calyxes) are noticeably bitter and will throw off any preparation you’re making if you leave them on, so take the time to remove them along with the stems.

I find that they’re easy to pinch off with your fingers, and I usually put my littles on this task. They can work through a whole bowl of lilacs quickly, and it’s the perfect job for tiny hands.

A full gallon of loose sprays yields about a quart of cleaned florets, which is plenty for a small batch of jelly or a quart of syrup.

Only harvest from shrubs that haven’t been sprayed with pesticides or herbicides, and avoid lilacs growing right alongside busy roads. If you don’t have a lilac of your own, ask a neighbor with an established shrub, as most lilac owners are happy to share during a good bloom year.

Lilac Recipes

Once you’ve got a fragrant bowl of cleaned florets, the question is what to make with them. Here are the recipes worth trying with your lilac harvest, starting with the two preserves I make every year (lilac jelly and lilac wine) and then moving through the lighter infusions, frozen desserts, baked goods, drinks, and homemade body products.

Most are quick afternoon projects, and several double as beautiful gifts.

Lilac Jelly

Lilac jelly is the first thing I make every spring because it’s the fastest way to capture the flavor in a shelf-stable form, and the finished jars are some of the prettiest preserves on our pantry shelf. The flavor is mild and honey-sweet rather than aggressively floral.

The technique is the same one you’d use for making any floral jelly: brew a strong lilac infusion (the “tea”), combine it with sugar and pectin, bring to a gel stage, and either water-bath can or refrigerate. The same basic method works for dandelion jelly, violet jelly, peony jelly and other floral preserves, with lilac landing somewhere between dandelion’s honey-sweetness and violet’s floral intensity.

Lilac Wine and Mead

Lilac wine is the slow project of the lilac season, the one I start in May and don’t open until well into the following winter. The flavor mellows from sharp and floral when young to soft and almost honey-like once it’s had a year in the bottle. It’s become the household favorite for the adults, and a glass of it in February tastes exactly like the day in May we picked the flowers.

The method is the same as any other flower wine or mead, with sugar and water replacing the natural sugars and water in fruit. To make a mead or honey wine instead of a plain wine, just substitute honey for the sugar at a roughly 1:1 ratio by weight.

• Lilac Wine (or Mead)

Lilac Sugar, Syrup, and Infused Honey

If you’re not in the mood to can or ferment, the simple lilac infusions are the fastest way to get that floral flavor into your kitchen. Lilac sugar is just clean dry florets layered with granulated sugar in a jar, left for a week or two until the sugar takes on the scent. Lilac simple syrup is the liquid version of the same idea, perfect for cocktails, lemonades, and drizzling over berries.

Lilac infused honey might be the prettiest of all, with the petals visible in the jar like an edible arrangement. All three preparations make beautiful gifts when packed into small jars with a ribbon, and they all keep for months as long as they’re stored in a cool spot.

• Lilac Sugar
• Lilac Simple Syrup
• Lilac Infused Honey

Lilac Ice Cream, Custards, Pudding, and More

As temperatures start to warm up in spring, I start planning ahead for ice cream, and the floral flavor of lilac translates beautifully into a custard base. Steep clean florets in warm cream for about thirty minutes, strain, and then proceed with whatever ice cream method you usually use. The floral note is gentle enough that it doesn’t overpower the cream. A few springs back I made dandelion and honey ice cream using the same approach, and it works just the same with lilacs.

Beyond ice cream, lilac plays well with all the creamy desserts of late spring: rice pudding, posset, panna cotta, sherbet. Lilac popsicles are the easiest, and they work whenever the kids are too impatient for the ice cream churn.

• Lilac Lemon Grapefruit Sherbet
• Lilac Ice Cream
• Lilac Honey Posset (old-fashioned custard)
• Lilac Rice Pudding
• Lilac Popsicles

Lilac Cake Recipes

The sweet floral qualities of lilacs make for a delightful cake, and the easiest entry point is folding lilac sugar or lilac syrup into a basic batter you already love. The flavor pairs beautifully with lemon and almond, and a lilac-infused buttercream over a simple vanilla layer cake is one of those desserts that looks like a special occasion without much extra effort.

They work well in classic cakes, as well as bundt cakes, cupcakes and shortcakes too!

• Giant Lilac Scented Strawberry Shortcake
• Lemon & Lilac Bundt Cake
• Small Batch Lilac Chocolate Cupcakes
• Lilac Cake with Matcha Glaze (Gluten Free)
• Lilac Honey Cake

Lilac Cookies & Donuts

Smaller-format desserts are arguably the most fun way to use a lilac harvest. A dusting of lilac sugar on the outside of a warm donut, folded into a cornmeal cookie, or sprinkled across a batch of scones carries the floral flavor without needing any complicated technique.

Scones are a good first project, and baked donuts are just as easy.

• Lilac Cornmeal Cookies
• Lilac Shortbread
• Lilac and Almond Scones
• Strawberry Jelly Donuts with Lilac Sugar
• Baked Lilac Donuts

Lilac Tarts, Cheesecakes, and Pavlovas

Some desserts give lilacs the spotlight in a way the simpler cakes and cookies can’t, and tarts, cheesecakes, and pavlovas really impress. The unifying trait is open structure: a cheesecake’s creamy expanse, a tart’s visible filling, and a pavlova’s marshmallowy meringue all give the floral note room to come through without competing with heavy batter or frosting.

They’re also some of the prettiest lilac desserts you can put on a table, which makes them favorites for spring parties and Mother’s Day brunches.

• Lilac and Blackberry Pavlovas
• Lilac Dream Vegan Cheesecake
• Lilac and Violet Panna Cotta Tart

Lilac Drinks

Spring is when we put away the heavy winter drinks and bring out the light, floral cocktails and mocktails, and lilac is the perfect bridge ingredient for that shift. Most lilac drink recipes lean on either lilac simple syrup or a lilac cordial as the base, both of which keep for weeks in the fridge and make assembling the actual drinks easy.

You can make fancy cocktails or mocktails, or keep it simple with something like lilac lemonade or tea.

Cocktails and Mocktails

• Lilac Lemon Fizz Mocktail
• Lilac 75 Cocktail
• Lilac Martini
• Lilac Bees’ Knees Cocktail

Zero Proof Drinks

• Lilac Water
• Fermented Lilac Tea
• Lilac Lemonade

Lilac Body Products

Beyond just eating lilacs, the same astringent quality that gives them their slight pucker on the tongue makes them a great addition to homemade body products. Lilac florets infused into witch hazel for a week or two make a gentle face toner, and the same infused base works for splash-style astringents and refreshing skin sprays.

Years ago I picked up a lilac solid lotion bar at a farmer’s market and loved using it on special occasions. When it finally ran out I missed it terribly, and that’s part of what got me thinking about making more of my own lilac body products at home. Bath truffles, milk baths, and infused face creams are all very giftable, and they all do well with lilacs as the featured fragrance.

• Lavender Face Cream with Lilacs and Violets
• Lilac Bath Truffle
• Lilac Milk Bath

Medicinal Uses of Lilacs

Though I cannot find much in the way of modern verification or clinical studies around the medicinal uses of lilacs, the flowers have a long history of use in folk herbalism. The most often-cited reference is Mrs. M. Grieve’s classic A Modern Herbal, first published in 1931, which describes the following traditional folk-remedy properties:

• Antiperiodic. Lilac flowers were historically used as a folk remedy to help strengthen the system and prevent the recurrence of disease after a patient had healed, said to be specifically useful after cases of malaria.
• Astringent. Tasting the raw flowers you can pick up some of the astringent qualities, as they make your mouth dry and pucker a bit along with their floral flavors. This astringent quality is what makes them useful in skin care products.
• Vermifuge. As another folk remedy noted by Grieve, lilacs have been used for intestinal worms, as well as for gastric discomfort and gas.

Regardless of the purpose, the most common medicinal lilac preparation is a tincture, made the same way as the lilac cordial, but without the added sugar. These historical uses are shared for reference and not as medical advice. If you’re interested in using any herb medicinally, work with a qualified herbalist or healthcare provider, especially if you’re pregnant, nursing, or taking medications.
