Homemade Lychee Syrup

This lychee syrup recipe is light, floral, and intensely fragrant – made with fresh or canned lychees. It’s a fragrant syrup that adds tropical sweetness to cocktails, mocktails, boba teas and sparkling drinks.

If you are into other highly fragrant fruit syrups, you’ll also love this exotic fig syrup or strawberry simple syrup.

Lychee syrup recipe formula

This lychee syrup recipe uses a 1:1 ratio – equal parts sugar to liquid (lychee juice plus water) – which gives you a syrup that lets the floral lychee flavor come through cleanly. At 1:1 it’s light enough for sparkling drinks and bubble tea without tipping sweet, and it dissolves instantly into cold liquids which matters when you’re building a cocktail or mocktail.

If you want a thick lychee syrup that’s more concentrated use a 2:1 ratio by doubling the sugar while keeping the liquid the same. The lychee aroma becomes more intense at 2:1 but the syrup is noticeably heavier, and in something like a sparkling water spritzer it can overpower the drink quickly.

Ingredients

• Lychees – fresh, canned, or frozen all work. Fresh lychees give the brightest, most aromatic syrup but require peeling and pitting. Canned lychees are the easier everyday option. If using frozen, thaw fully and use any released juice.

• Granulated white sugar – keeps the lychee flavor front and center without adding anything of its own. Coconut sugar works as a substitute for a deeper, slightly earthy note, and honey gives a softer floral sweetness that actually complements lychee well – but it changes the texture slightly.

• Water – only needed if you don’t have enough lychee juice to reach your liquid measurement.

• Lemon juice – optional but worth it. A small squeeze added off the heat brightens the syrup and keeps the lychee flavor from reading as flat.

How to make lychee syrup

Peel and pit your lychees, collecting as much of the juice as you can as you go – fresh lychees release more liquid than you’d expect and that juice is where most of the flavor lives. Add the fruit, collected juice, sugar, and water to a small saucepan over medium heat and stir gently as it warms.

Once the sugar is dissolved and the mixture starts to look glossy, give the fruit a light mash with the back of a spoon. You’re not trying to make a puree – just breaking it down enough to release the aromatic compounds sitting in the flesh. Let it simmer gently for about 5 minutes until the syrup smells noticeably floral, then pull it off the heat.

This is where most recipes rush things: let it steep for 15 to 20 minutes before straining. The flavor deepens significantly during that window and skipping it is the most common reason homemade lychee syrup tastes thin. Strain through a fine mesh sieve, pressing gently on the solids to get the last of the juice out without pushing pulp through. Stir in the lemon juice off the heat, cool completely, then bottle.

Lychee syrup recipe using canned lychees

Drain the canned lychees, reserving the juice. Add the lychee fruit and enough of the reserved juice to make 1 cup of liquid (or supplement with water if needed) to a small saucepan along with the sugar.

Heat gently over medium, stirring until the sugar dissolves. Since the fruit is already soft, you can lightly mash it to release extra flavor or leave some pieces whole for texture. Let the syrup simmer for 3–5 minutes until fragrant, then remove from heat and let it steep for 10–15 minutes to deepen the flavor.

Strain through a fine mesh sieve, pressing gently on the solids. Stir in lemon juice if using, let cool completely, and transfer the lychee simple syrup to a clean jar or bottle for storage.

Tips and notes from recipe testing

• The steeping time is not optional. 15 to 20 minutes off the heat is what separates a flat syrup from a genuinely fragrant one. Set a timer and don’t rush it.

• Press the strained solids gently – firmly enough to extract juice, lightly enough not to push pulp through the sieve. Cloudy syrup isn’t unsafe but it shortens shelf life and affects the look in clear drinks.

• Add lemon juice after straining and off the heat, not before. Heat cooks off the brightness and you lose the lift it’s supposed to provide.

• “Litchi syrup” is just another spelling of the same fruit so if you’re searching for litchi syrup recipe results, you’re making the same thing.

• For a clearer syrup, line your sieve with a piece of muslin or a coffee filter. It takes longer to drain but the result looks much cleaner in cocktails and sparkling drinks.

Flavor notes

• Sweetness: medium to high (adjustable by ratio)
• Primary note: floral tropical lychee
• Secondary note: light honeyed pear and grape tones
• Overall profile: delicate, aromatic, and refreshing with soft fruit complexity

Lychee syrup uses

Homemade lychee syrup is one of the most versatile fruit syrups you can make. It’s light enough for sparkling drinks, fragrant enough for cocktails, and gentle enough not to overwhelm delicate teas.

• Bubble tea and boba – perfect as lychee syrup for boba, where the floral sweetness works as both the flavoring and the sweetener in one. It pairs especially well with jasmine milk tea or coconut milk bases where the floral notes reinforce each other.

• Cocktails – this is where homemade lychee syrup really earns its place. It adds fragrant sweetness to vodka-based drinks, gin sours, and lychee martinis without the artificial edge you get from store-bought lychee liqueur. Using as a lychee syrup for cocktails, 1:1 is the right ratio to pick.

• Mocktails and sparkling drinks – stir into sparkling water with a squeeze of lime for a simple lychee spritzer, or use as the base for a lychee lemonade. The carbonation amplifies the floral aroma in a way that still drinks feel like they have layers.

• Iced tea – pairs beautifully with green tea, jasmine tea, and white tea where it complements rather than competes. Works well in cold brew tea specifically.

• Lychee lemonade – one of the most popular uses. The citrus sharpness and the floral lychee are a natural combination. Start with equal parts lemon juice and syrup, top with still or sparkling water, and adjust sweetness from there.

• Dessert drizzle – spoon over vanilla panna cotta, ice cream, or sponge cake. For dessert use the 2:1 version is worth making as it’s thicker and the flavor is more concentrated.

Storage & shelf life

Stored in a sterilized, airtight glass jar in the fridge, the lighter lychee syrup recipe keeps well for up to 2 weeks. By day 3 or 4 the syrup is fully settled and the flavor is at its most rounded – the floral notes that can sometimes smell sharp right after making mellow into something more cohesive. The thicker version lasts significantly longer, up to 3 to 4 weeks, because the higher sugar concentration slows spoilage.

Lychee syrup recipe – especially the fresh fruit version – is more perishable than most simple syrups because of the natural fruit content. If you want to preserve lychees in syrup for longer, freeze it in an ice cube tray (roughly 2 tablespoons per cube) and transfer to a sealed bag once solid.

Before every use, check for cloudiness that wasn’t there before, any fermentation smell, bubbling, or visible mould. Fresh fruit syrups can turn faster than sugar-only syrups, so err on the side of caution and if something seems off, discard it.

Variations

• Rose lychee syrup – add a small splash of rose water after straining, off the heat. Start with half a teaspoon and taste as rose water is strong and can easily take over.

• Lychee ginger syrup – simmer with 3 to 4 slices of fresh ginger alongside the lychee. Adds warmth and a subtle heat that works really well in cocktails.

• Lychee mint syrup – steep a small handful of fresh mint leaves in the syrup during the cooling phase, then strain out with the fruit. Clean and refreshing.

• Lychee cordial – increase the lemon juice slightly and use as a cordial concentrate diluted 1:4 with still or sparkling water. Closer to a squash than a syrup, great for non-alcoholic drinks.r cardamom pod while simmering.
