Khmer Sugar Syrup

5.0 from 1 vote

Khmer sugar syrup is a quiet kitchen staple in Cambodia. It is the sweet base behind colourful snow cones, cold smoothies, and many traditional Khmer desserts. With just water, sugar, and a little vanilla, you can make a smooth syrup at home.

The syrup is lightly golden, pourable, and softly fragrant. It is not thick like caramel. Instead, it stays fluid so it mixes easily into drinks and spooned-over desserts. This small batch takes only a few minutes on the stove, and it keeps in the refrigerator for about a week.

What You Need

This recipe uses three everyday ingredients: water, white sugar, and pure vanilla extract. There is nothing else to buy. The sugar dissolves into the water as it simmers, and the vanilla adds a gentle aroma at the end.

Use a small pot so the syrup does not spread too thin across the base. A pot that is too wide can make the liquid reduce too quickly.

Equipment

Small pot or saucepan: To simmer the water, sugar, and vanilla together until the sugar dissolves and the syrup reduces slightly.
Wooden spoon or heatproof spatula: To stir the mixture while it heats so the sugar dissolves evenly.
Measuring cups or kitchen scale: To measure the sugar. To measure the water accurately.
Measuring spoons: To measure the vanilla extract.
Heatproof jar or container with a lid: To store the cooled syrup in the refrigerator.

How to Make Khmer Sugar Syrup

Step 1: Combine the Ingredients

Pour 1 cup of water into a small pot. Add 2 cups of sugar and 1 teaspoon of pure vanilla extract.

Stir gently with a wooden spoon so the vanilla mixes into the water. The sugar will not dissolve yet.

Step 2: Simmer Until the Sugar Dissolves

Place the pot over medium heat. Stir occasionally as the mixture heats.

Keep simmering until the sugar is fully dissolved and the liquid has reduced slightly. The syrup should look clear, not grainy. Remove the pot from the heat.

Step 3: Cool and Store

Leave the syrup in the pot until it cools completely. Then pour it into a clean jar or container with a tight-fitting lid.

Store the jar in the refrigerator. The supplied recipe notes that the syrup keeps for about one week.

Cooking Tips

Stir gently rather than vigorously. You want the sugar to dissolve, not to splash up the sides of the pot.

Keep an eye on the pot as it simmers. The syrup can reduce faster than expected once the sugar dissolves, and you do not want it to become too thick.

Let the syrup cool completely before sealing the jar. Trapping steam inside the container can thin the syrup and affect storage.

How to Serve

Khmer sugar syrup is used as a sweetener and a finishing touch. Spoon it over Cambodian desserts and drinks such as sweet puddings, coconut-based sweets, or shaved ice.

It also mixes into cold drinks and smoothies. Add a spoonful to a glass of iced tea or soda when you want a little sweetness with a soft vanilla note.

For a colour twist, the supplied recipe notes that a drop of food colouring can turn the syrup red or another colour for snow cones.

Recipe Notes

The syrup is a sweet liquid made from sugar and water. It is a time-and-temperature control food, which means it should be kept in the refrigerator for safety. Do not leave it at room temperature for long periods.

This recipe follows the traditional Khmer Krom method of simmering water, sugar, and vanilla until the sugar dissolves and the syrup reduces. The same preparation appears in the original Khmer Krom sugar syrup recipe with identical quantities.

Cambodia is also known for its Kampong Speu palm sugar, a protected regional product. That palm sugar is a different ingredient from the white sugar used here, but it is part of Cambodia’s broader sugar culture.
