Here is how to make lychee syrup in one line: gently simmer peeled, pitted fresh lychees, or the syrup and fruit straight from a can of lychees, with sugar and a little water, brighten it with a squeeze of lemon, then strain. What you get is a fragrant, rose-and-pear-scented syrup that stirs into bubble tea, iced tea, lemonade, sparkling water and cocktails. It is one of the easiest fruit syrups to love, and below you will find a full lychee syrup recipe with real amounts, a ratio table, a fresh-versus-canned comparison and storage notes.
What Lychee Syrup Is
Lychee syrup is a flavoured fruit syrup: a sweet, pourable liquid that carries the perfume of ripe lychee. The flavour is the whole reason people chase it. It is floral and sweet-tropical, with a note that reads a little like rose and a little like pear, plus a faint muscat, grape-like edge. That perfumed quality is delicate, which shapes how you cook it: a long, hard boil dulls the aroma and pushes the fruit toward a flat, cooked taste, so the trick is gentle heat and a short simmer.
Lychee is a beloved summer fruit across East and Southeast Asia, from southern China to Vietnam, Thailand and beyond, where its translucent, jelly-like flesh is prized in the hottest months. It is also one of the most popular bubble-tea flavours in the world, which is exactly why a jar of homemade syrup is so handy. This guide stays focused on the lychee syrup itself.

Fresh or Canned Lychees
You can make a lovely lychee simple syrup two ways, and both are good. Fresh lychees, in season, give the brightest, most floral result, but they need peeling and pitting and they only appear for a short window each year. Canned lychees in syrup are the shortcut worth knowing: the fruit is already peeled and pitted, it is available year-round, and the packing syrup is itself sweet lychee liquid you can build straight into the recipe. In other words, with a can you get a head start on both the fruit and the sugar. Here is how the two compare.
| Option | Effort | Flavour | Season |
|---|---|---|---|
| Fresh lychees | More: peel and pit each fruit | Brightest, most floral and perfumed | Short summer window |
| Canned lychees in syrup | Less: already peeled, pitted and sweet | Rounder and reliably sweet, a touch less lively | Year-round |
How to Make Lychee Syrup, Step by Step
The method is quick and forgiving. The key techniques are simple: use peeled, pitted fruit, crush it so the flesh gives up its perfume, simmer gently rather than hard, add a squeeze of lemon to keep everything bright, and strain for a clear syrup. Taste as you go, since lychees vary in sweetness.
Lychee syrup ratios at a glance
Every version starts from the same idea: sugar dissolved in liquid, carrying crushed lychee. Shift the sugar-to-water ratio to change the body, from a loose pour to a thick, spoon-clinging syrup. These all build on a plain sugar base, and the deeper mechanics of a 1:1 versus 2:1 sugar syrup live in the simple syrup guide linked above. Keep the fruit at about 1.5 cups of peeled, pitted lychees across all three styles.
| Syrup style | Sugar : water ratio | Texture | Best for |
|---|---|---|---|
| Thin (light) | 1 : 1 | Loose and pourable | Iced tea, spritzers, a quick soda |
| Standard | 1.5 : 1 | Medium body, balanced | Everyday use and bubble tea |
| Rich (thick) | 2 : 1 | Thick, clings to a spoon | Cocktails, drizzling, longer keeping |
Ingredients
- About 1.5 cups peeled, pitted fresh lychees, or one can of lychees in syrup (use both the fruit and the packing syrup)
- 1/2 to 3/4 cup sugar (use the lower amount if you are also using the sweet syrup from a can)
- About 1/2 cup water (or the drained syrup from the can, topped up with a little water)
- 1 teaspoon lemon juice
Method for fresh lychees
- Peel and pit. Peel the fresh lychees, tear the flesh away from the seed, and discard the peel and pits. You are aiming for about 1.5 cups of fruit.
- Crush lightly. Roughly crush or chop the flesh so it will release its floral juice into the syrup.
- Warm the sugar and water. In a small saucepan, combine the sugar and water over medium heat and stir until the sugar fully dissolves. There is no need to boil it hard.
- Add the fruit. Stir in the crushed lychees and bring to a bare, gentle simmer.
- Simmer briefly. Let it simmer softly for just 5 to 8 minutes, so the perfume infuses without cooking off. Keep it well below a hard, rolling boil.
- Steep off the heat. Take the pan off the heat and let the fruit steep in the warm syrup for 15 to 20 minutes to draw out more aroma.
- Add lemon and strain. Stir in the teaspoon of lemon juice, then pour the syrup through a fine mesh sieve into a clean jar, pressing gently on the fruit. Straining is what turns pulpy fruit into a smooth, clear syrup.
- Cool and bottle. Let the syrup cool completely, then seal and refrigerate.
Method for canned lychees (the shortcut)
- Separate fruit and syrup. Drain the can, keeping both the lychees and the packing syrup.
- Crush the fruit. Roughly crush or chop the canned lychees so they release their flavour.
- Build the base. Pour the reserved packing syrup into a saucepan, top it up to about 1/2 cup of liquid with a splash of water, and add the smaller amount of sugar (the can is already sweet, so you need less). Warm over medium heat until the sugar dissolves.
- Add the fruit and simmer gently. Stir in the crushed lychees, bring to a bare simmer, and cook softly for about 5 minutes.
- Steep, lemon, strain. Off the heat, steep for 15 minutes, stir in the lemon juice, then strain into a clean jar and cool before sealing.

How to Use Lychee Syrup
The headline use is lychee bubble tea: stir the syrup into cooled tea and milk over ice with cooked tapioca pearls for a floral, sweet cup. The full building method, tea base and pearls are covered in the boba milk tea guide, so keep this jar as the flavour and let that page handle the build. Beyond boba, lychee syrup is wonderfully versatile:
- Lychee iced tea, stirred into cooled black or green tea over ice
- Lemonade, for a floral, rosy twist
- Sparkling water, for a quick homemade lychee soda
- Cocktails and mocktails, where lychee shines with gin, vodka, sparkling wine and rose
- A splash over a fruit salad, shaved ice or a scoop of vanilla ice cream
Start with a small pour, taste, and add more, since lychee is naturally sweet and perfumed and a little carries a long way. A final squeeze of fresh lemon or lime in the glass keeps a tall, iced drink from tasting flat.
Storage and Shelf Life
Because this is a fresh-fruit syrup with no preservatives, treat it like something perishable. Keep it in a clean, airtight jar or bottle in the refrigerator and use it within about 2 to 3 weeks. Always pour with a clean spoon or straight from the bottle rather than dipping used utensils in. Watch for the usual signs that a homemade syrup has turned: new cloudiness, an off or fermented smell, fizzing, or any film or fuzz. When in doubt, throw it out. To keep a batch longer, freeze portions in an ice-cube tray and thaw a cube whenever you want to flavour a drink.
A Light Food-Safety Note
Nothing here is medical. Work with clean equipment and a clean, dry jar, let the syrup cool fully before you seal it so condensation does not encourage spoilage, and keep it cold between uses. This recipe sweetens with plain sugar; if you ever swap in honey, never give honey-sweetened drinks to infants under 12 months. Lychee syrup is a sweet flavouring to enjoy for its perfume and taste, not a health product, and individual responses to any food vary, so this is general food-and-drink information, not medical advice. With a jar in the fridge, a plain glass of iced tea, sparkling water or bubble tea is only a spoonful away from tasting like a summer treat.
