How to Make Grass Jelly Drinks at Home: A Bubble Tea Lover's Guide

Grass jelly drinks are a delightful addition to the bubble tea family, offering a subtly herbal, cooling element that pairs beautifully with creamy milk teas, fruity iced teas, or simple syrups. At its core, a homemade grass jelly drink combines prepared grass jelly (a dark, jelly-like dessert made from the leaves of the mesona plant) with your choice of liquid base—such as milk tea, fruit juice, or sweetened soy milk—and often a sweetener or syrup. The result is a refreshing, chewy beverage that's perfect for warm days or as a unique treat for gatherings. Whether you're new to bubble tea or a seasoned enthusiast, making grass jelly drinks at home is straightforward and endlessly customizable.

What Is Grass Jelly and Why Does It Work in Drinks?

Grass jelly, sometimes called cincau in Southeast Asia, is made by boiling the leaves and stalks of the mesona plant, then cooling the liquid until it sets into a dark, slightly bitter, herbal-flavored jelly. In drinks, it is usually cut into cubes or scooped into thick strands. Its mild bitterness balances the sweetness of syrups and milks, and its soft, slippery texture—similar to but more delicate than tapioca pearls—adds a pleasant chewiness that makes every sip interesting.

Choosing Your Grass Jelly: Fresh, Canned, or Powder

You can prepare grass jelly at home from scratch, but most home recipes start with a convenient base:

Canned grass jelly: Pre-made, lightly sweetened or unsweetened, sold in Asian grocery stores. It comes as a solid block that you cube. This is the easiest option and ready to use immediately.
Grass jelly powder: A mix that you dissolve in boiling water, then let set. It usually makes a large batch and can be customized in firmness. Follow the package instructions—typically, one packet uses about 500 ml (2 cups) of water and sets in 2–4 hours.
Fresh leaves: Traditional method, but time-consuming and harder to find. For home use, canned or powder is recommended.

For most drink recipes, start with unsweetened grass jelly so you can control the sweetness of the final drink.

Basic Grass Jelly Drink Recipe: Step-by-Step

This foundational recipe uses a simple syrup and milk tea base, but you can substitute the base with any of the variations below.

Ingredients for 2 servings:

1 cup (240 ml) prepared grass jelly, cut into 1 cm cubes
2 cups (480 ml) strong brewed black tea (or your favorite tea), cooled
1/2 cup (120 ml) milk (dairy or plant-based, such as oat or almond)
3–4 tablespoons simple syrup (adjust to taste; see step 1)
Ice cubes

Instructions:

Make simple syrup: Combine equal parts sugar and water (e.g., 1/2 cup sugar and 1/2 cup water) in a small saucepan. Heat over medium, stirring until sugar dissolves. Cool completely. Store extra in the fridge for up to 2 weeks.
Prepare grass jelly: If using a can, drain and cut the jelly into small cubes. If using powder, prepare according to package directions and set aside.
Divide jelly and ice: Place a generous spoonful of grass jelly cubes in each glass, then add ice cubes to fill about halfway.
Mix tea and milk: In a pitcher, combine chilled tea, milk, and 3 tablespoons of simple syrup. Stir well and taste; add more syrup if desired.
Pour and serve: Pour the tea mixture over the ice and jelly. Stir gently before drinking. Serve with a wide straw or a spoon to enjoy the jelly chunks.

For a non-dairy version, replace the milk with coconut milk, soy milk, or simply omit it and use a stronger tea with extra syrup.

Flavor Variations: From Classic Milk Tea to Fruity Iced Drinks

Grass jelly pairs with a wide range of flavors. Here are some popular options:

Drink Style	Base Liquid	Sweetener / Syrup	Add-Ins (optional)
Classic Grass Jelly Milk Tea	Black tea + milk	Brown sugar syrup	Tapioca pearls
Grass Jelly Soy Milk	Unsweetened soy milk	Honey or simple syrup	None
Grass Jelly Fruit Tea	Green tea or jasmine tea + fruit juice (mango, lychee, passion fruit)	Fruit syrup or simple syrup	Fresh fruit chunks
Grass Jelly Limeade	Sparkling water + fresh lime juice	Simple syrup	Mint leaves
Grass Jelly Coffee	Cold brew coffee + milk	Simple syrup or vanilla syrup	Coffee jelly (optional)

For a more indulgent treat, drizzle brown sugar syrup inside the glass before adding jelly and milk for a beautiful layered effect.

Grass Jelly Drinks for Get-Togethers: Alcohol-Free Serving Ideas

Because grass jelly is naturally alcohol-free and pairs with many non-alcoholic bases, it is ideal for parties and family gatherings. Set up a DIY grass jelly drink bar where guests can choose their base (milk tea, fruit juice, soy milk, or sparkling water), add grass jelly cubes, and finish with syrups, fresh fruit, or boba. Provide wide straws and long spoons. For a festive touch, serve in clear glasses to show off the dark jelly against colorful liquids. Pair the drinks with light snacks such as spring rolls, fruit skewers, or coconut-based desserts.

Tips for Perfect Grass Jelly Drinks

Chill everything: Use cold tea, cold milk, and plenty of ice to keep the jelly firm and refreshing.
Cut jelly small: Cubes about 1 cm are easy to sip through a wide straw; larger pieces are better for spoon use.
Adjust sweetness gradually: Start with less syrup; you can always add more, but you can't remove it.
Make ahead: Grass jelly can be prepared up to 3 days in advance and stored in the fridge in a covered container with a little water or sugar syrup to prevent drying.
Use strong tea: Brew tea double strength so it doesn’t get diluted by ice and sweetener.

By mastering a basic grass jelly drink recipe, you open the door to countless homemade bubble tea–style creations. Enjoy experimenting with flavors and sharing these chewy, refreshing beverages with friends and family.
