Why You’ll Love This Recipe
Unlike heavy dairy desserts, this clear tropical pudding uses coconut water as its base, allowing the floral notes of the fresh fruit to shine. Simmering the fruit directly in the liquid infuses the whole jelly with an authentic tropical flavor.

Ingredients For Rambutan Jelly
- 2.5 cups coconut water
- 2 tsp agar agar powder
- 10 fresh rambutans
Instructions
Step 1: Prep the Fruit
Peel the fresh rambutans and slice the juicy flesh away from the hard inner seeds. Discard the seeds and set the fruit pieces aside.

Step 2: Whisk the Base
Pour the coconut water into a saucepan or pot. Add the agar agar powder and whisk it thoroughly until entirely combined and no lumps remain.
Step 3: Infuse and Simmer
Add the peeled rambutan pieces into the pot with the liquid. Bring the mixture to a simmer over medium heat and let it simmer for 5 minutes. This is a crucial step because it activates the gelling properties of the agar agar while simultaneously drawing out the fragrant rambutan flavor into the liquid.

Step 4: Separate the Fruit
Turn off the heat. Using a slotted spoon, remove the rambutan pieces from the liquid and add them to the bottom of a glass bowl or mold.
Step 5: The Two-Step Pour (For Perfect Fruit Placement)
To get your rambutan fruit pieces beautifully postioned on top, pour just a small amount of the hot liquid into the mold—just enough to cover the rambutan pieces. Place the mold into the freezer for 10 minutes to let this base layer set.

Step 6: Unmold and Serve!
Once set, gently run a toothpick or a thin knife around the outside edge of the mold to separate the jelly from the glass. Place a serving plate upside down over the top of the bowl, firmly hold both, and flip them over to release the pudding. Slice into clean pieces and serve cold!

Common Questions
Yes, you can use standard gelatin if you do not need the recipe to be vegan or plant-based. However, keep in mind that gelatin needs to be bloomed in cold water first and should never be boiled, whereas agar agar must be simmered for 5 minutes to activate its gelling properties. Agar agar is also more suitable for hot climates (such as Malaysia, where I live). In warm climates, gelatin jelly will turn into a puddle, whereas agar agar jelly will remain firm and hard. Gelatin is also more squishy and will melt when heated. Agar agar remains hard and firm once set (even in hot climates).
Absolutely. If fresh rambutans aren't in season, canned rambutans in syrup work beautifully.
Rambutans are incredibly versatile! If you have extra fruit left over, you should absolutely try making a batch of creamy dairy free rambutan ice cream, blending up a refreshing rambutan juice, or cooking down a small-batch rambutan jam to spread on your morning toast.
Because we use a smart "two-step pour" method to keep the fruit from floating, the base layer takes just 10 minutes in the freezer. After adding the remaining liquid, the pudding will take about 4 hours in the refrigerator to cool completely and set into clean, sliceable squares.
