Khanom Salim (Sweet Mung Bean Threads with Coconut Syrup)

Introduction

Khanom Salim is a Thai dessert of delicate mung bean threads served cold with jasmine-scented coconut syrup—it takes about an hour total, requires a salim press (a specialized tool with small holes), and delivers a silky, refreshing bowl perfect for warm weather. The mung bean dough cooks down to a clear, translucent state before being pressed into thin strands that float in ice and sweet coconut milk. If you enjoy light, coconut-forward sweets, this one is worth the small equipment investment.

Recipe Details

• Prep Time: 10 minutes
• Cook Time: 50 minutes
• Total Time: 60 minutes
• Servings: 4

Ingredients

Dough

• 1 cup (100 g) mung bean flour/starch
• 5 cups (550 g) water
• Food coloring

Simple syrup

• 2 cups (400 g) white granulated sugar
• 1 cup (110 g) water
• 1 cup (150 g) coconut milk
• Jasmine flavoring
• Crushed ice

Instructions

1. Mix the mung bean flour and water until smooth. Separate it into 2 or 3 portions, and mix 1-2 drops of food coloring into each portion to color it.
2. Transfer each piece of dough into a pan, and put it on the stove over low heat.
3. Stir constantly for about 15 minutes,until the dough is cooked and has become clear.
4. Put all the dough in the salim press. Press the dough into a bowl of cold water.
5. Make a simple syrup by mixing the sugar and water together over a stove over low heat until the sugar is dissolved.
6. Put the noodles into a small bowl with crushed ice. Top with jasmine-flavored coconut milk and the sugar syrup.

Variations

Skip the food coloring – you’ll get pale, off-white threads instead of colored ones, but the texture and flavor remain identical. This works well if you prefer a cleaner, less visually striking presentation.

Use different jasmine intensity – if your jasmine flavoring is very strong, reduce it to half the amount and taste before adding more. If it’s mild, you can increase it slightly. The syrup should smell floral without tasting like perfume.

Make the syrup ahead – prepare the sugar syrup the day before and chill it. This cuts your assembly time in half and lets the flavors meld further.

Substitute coconut cream for coconut milk – use the thicker, richer cream layer from a can of full-fat coconut milk (or half coconut cream and half milk). The threads will float in a more luxurious, heavier syrup.

Color only one portion – if you want a simpler look, color only one batch of dough and leave the others plain. Mix them for a two-tone effect.

Tips for Success

Stir constantly during the 15-minute cook – the dough thickens and sticks easily if you pause. Keep your pace steady and scrape the bottom and sides of the pan regularly to prevent burning.

Wait for full transparency – the dough will look cloudy or opaque halfway through cooking. Keep going until it’s visibly clear and glossy, not just lighter in color.

Work quickly after pressing – once the threads are pressed into the cold water, leave them there only briefly to set. If they sit too long, they may become mushy or clump together.

Chill everything before serving – assemble the bowl just before eating. Ice melts fast, so use plenty of crushed ice and serve immediately for the best texture contrast.

Test your jasmine flavoring first – add a tiny drop to a small spoonful of the coconut milk and taste it before committing the full amount to the syrup.

Storage and Reheating

FAQ

Do I need a salim press, or can I use something else?

A salim press is the traditional tool designed to create thin, even threads. A ricer or fine-mesh sieve won’t produce the same delicate strands. If you don’t have a press and can’t source one, this recipe is difficult to replicate successfully.

What if my mung bean dough doesn’t become clear after 15 minutes?

It may take a few extra minutes depending on your stove’s heat and the exact flour moisture. Keep stirring; once it turns translucent and glossy, it’s done. Undercooked dough will be cloudy and gritty; overcooked dough will darken and burn at the edges.

Can I use a different flavor instead of jasmine?

Yes—rose water, pandan extract, or a light cardamom-infused syrup all work well with coconut milk and mung beans. Use the same small amount to avoid overpowering the delicate threads. Avoid strong flavors like coffee or chocolate, which clash with the subtle sweetness.

How much does the salim press cost, and where do I find one?

A basic salim press typically runs $10–25 USD and is available through Asian grocery suppliers, specialty kitchen shops, and online retailers specializing in Southeast Asian tools. It’s a single-use tool, so check your local Asian market first to see if you can try or borrow one before committing to a purchase.
