How to Make Pandan Juice and Concentrated Pandan Extract at Home

To make homemade pandan juice, cut fresh or thawed pandan leaves into short pieces, blend or pound them with a small amount of water, then strain the green pulp through a fine cloth and squeeze out every drop. To turn that juice into a concentrated pandan extract, refrigerate it in a closed jar for one to two days. A thick, dark green layer settles to the bottom. Pour off the pale liquid on top, and the green sediment that remains is your concentrate.

The process takes about 15 minutes of active work and needs only leaves, water and a strainer. The rest of this guide explains what pandan is, how to recognize good leaves, and how to make the juice with a blender, a Thermomix or simple hand tools. It also covers how to use the juice in cakes and classic Thai sweets.

What Are Pandan Leaves and Why Does Thai Cooking Use Their Juice?

Pandan leaves are long, flat, sword-shaped leaves of the screwpine plant (Pandanus amaryllifolius), called bai toey in Thai. In Thai kitchens they are used much as vanilla is used in Western baking: as a fragrance that makes sweet and savory dishes smell rich and comforting.

How to recognize pandan leaves

• Shape: narrow, strap-like blades with a pointed tip, often 30–50 cm long. They grow in a spiral fan from a central stem, so bundles usually still show a pale base where the leaves joined.
• Color: glossy, deep emerald green on top and slightly lighter underneath. Fresh leaves look shiny and taut. Old leaves turn dull, yellowish or brown at the tips.
• Texture: firm and fibrous, a little like a thick blade of grass. A central ridge runs down the middle, and the edges may feel faintly rough.
• Aroma: whole leaves smell faint until you bruise or tear them. Then they release a sweet, grassy scent that many people compare to vanilla, freshly cooked jasmine rice and toasted nuts. The scent belongs to the same family as the one that makes fragrant rice smell fragrant.

What pandan juice contributes to a dish

Pandan juice adds three things: a natural soft green color, a gentle sweet-floral aroma, and a faint grassy freshness. It does not add sweetness or noticeable thickness. Because the juice carries both color and fragrance, Thai cooks blend it into batters, custards, coconut-milk desserts and doughs. Whole leaves only perfume the liquid they are steeped in.

Familiar Thai examples include:

• Khanom chan: a chewy, steamed layered dessert with alternating green pandan and white coconut stripes.
• Sangkaya bai toey: a pandan custard, often spread on soft bread or spooned over sticky rice.
• Lod chong: short green rice-flour noodles served in sweetened coconut milk with crushed ice.
• Khanom tuay: small coconut cup puddings, sometimes made with a green pandan base layer.

In savory dishes such as gai hor bai toey (chicken wrapped in pandan leaves), the whole leaf is used as an aromatic wrapper rather than as juice.

How pandan differs from similar-looking ingredients

• Lemongrass is also long and green, but it is a stiff, round stalk with a sharp citrus smell, not a flat, glossy leaf.
• Banana leaves are huge and broad and are used for wrapping. They give a mild, tea-like aroma rather than pandan's sweet scent.
• Bottled pandan essence or paste is a commercial flavoring. It is usually much brighter green, often from added food coloring, and its aroma can taste stronger and more artificial than fresh juice.

Pandan Juice vs. Concentrated Pandan Extract: What Is the Difference?

Pandan juice is the fresh, thin, green liquid squeezed from blended leaves. Concentrated pandan extract is the dense green sediment that separates from that juice after resting in the fridge. Both come from the same batch, so you get the concentrate without extra leaves.

How to Make Pandan Juice with a Blender

The standard method for homemade pandan juice is to blend chopped pandan leaves with a little water and strain the pulp through a fine cloth. The less water you use, the more intense the juice.

What you need

• Fresh or frozen pandan leaves (thaw frozen leaves first)
• Water
• A blender or food processor
• A fine-mesh sieve lined with cheesecloth, a nut-milk bag or a clean thin cotton cloth
• A bowl and a clean glass jar

Starting ratio

A practical starting point is roughly equal weights of leaves and water, for example about 100 g of pandan leaves to about 100 ml of water. Use the smallest amount of water that lets your blender run smoothly. Treat this as a guideline rather than a fixed rule: leaf freshness and blender power both change how much liquid you need.

Steps

1. Wash the leaves. Rinse each leaf under running water and wipe away any grit, especially near the base.
2. Trim. Cut off brown or dried tips and any very pale, tough base, which can taste bitter.
3. Cut into small pieces. Slice the leaves crosswise into pieces about 1–2 cm long. Short pieces stop the long fibers from wrapping around the blades.
4. Blend. Put the pieces in the blender with the water. Blend until the leaves become a fine, wet green pulp, scraping down the sides as needed. Add a spoonful more water only if the blender stalls.
5. Strain. Pour the pulp into the cloth-lined sieve set over a bowl.
6. Squeeze. Gather the cloth into a bundle and twist and squeeze firmly until no more liquid comes out. Most of the juice comes from this squeeze, not from passive draining.
7. Store. Pour the juice into a clean jar, close it and refrigerate it right away.

Freshly squeezed juice smells strongly of cut grass at first. The sweet, rice-like aroma becomes more noticeable once the juice is cooked into a dessert.

How to Make Pandan Juice with a Thermomix

To make pandan juice with a Thermomix, chop the leaves into short pieces, process them with a small amount of water at high speed until finely pulped, then strain and squeeze as usual. The Thermomix is useful here because its powerful blades break down fibrous leaves well with little water.

1. Wash, trim and cut the pandan leaves into pieces about 1–2 cm long.
2. Place the leaves and water in the mixing bowl, using a similar leaf-to-water ratio as for a blender.
3. Close the lid and process at high speed in short runs, about 30–60 seconds at a time. Stop to scrape down the bowl with the spatula between runs.
4. Repeat until the pulp looks fine and evenly wet. Check your model's manual for the recommended speed settings.
5. Pour the pulp into a cloth-lined sieve, squeeze firmly and refrigerate the juice in a closed jar.

Avoid the heating function. Heat dulls the bright green color and changes the fresh aroma, so cold processing gives the best juice.

How to Make Pandan Juice Without a Blender

You can make pandan juice without a blender by pounding, grating or finely chopping the leaves to break their fibers, then kneading them with water and squeezing the liquid through a cloth. Hand methods take more effort and usually yield a little less juice, but they work well.

Mortar and pestle

This is the traditional Thai approach. A heavy granite mortar, called krok in Thai, crushes plant cells very effectively.

1. Cut the leaves into thin strips or small pieces.
2. Pound a small handful at a time until the leaves look bruised, dark and mushy.
3. Move the pounded leaves to a bowl, add a little water and knead with your hands for a minute or two.
4. Squeeze through a cloth. Pound and squeeze any remaining pulp a second time if it still feels juicy.

Knife and hands

1. Slice the leaves crosswise as thinly as you can, then chop the slices until they are almost minced.
2. Put the chopped leaves in a bowl with a little water and rub and squeeze them firmly with clean hands, as if wringing out a sponge.
3. Strain through a cloth and squeeze hard.

Freezing to help the process

Freezing pandan leaves before you process them helps all hand methods. Ice crystals rupture plant cells, so thawed leaves release juice more easily when pounded or squeezed. Frozen pandan from Asian grocery stores can be used the same way.

Steeping is not the same as juicing

Simmering knotted pandan leaves in water or coconut milk makes a fragrant infusion, but it gives very little green color. Use steeping when you want aroma only, such as for rice, syrups or drinks. Use extraction when a recipe calls for pandan juice.

How to Make Concentrated Pandan Extract at Home

A homemade pandan extract recipe needs no added ingredients: you let fresh pandan juice settle in the fridge until the green solids sink, then pour off the clearer liquid on top. The dark green layer left behind is concentrated pandan extract.

1. Make the juice. Prepare pandan juice by any method above, using as little water as possible.
2. Rest it cold. Pour the juice into a tall, narrow, clean glass jar. A narrow jar makes the layers easier to see. Close it and refrigerate it for 1–2 days without stirring.
3. Watch for layers. The juice separates into a thin, pale yellow-green liquid on top and a dense, dark green sediment at the bottom.
4. Decant. Slowly pour or spoon off the pale liquid, stopping when you reach the thick green layer.
5. Keep the concentrate. What remains is your concentrated pandan extract. It should look thick and deeply green, with a strong pandan smell.

Don't throw away the pale liquid. It still carries some aroma and can replace plain water in sticky rice, jelly or a sweet drink.

How to store pandan juice and extract

Fresh pandan juice and concentrated extract contain no preservatives, so keep them refrigerated in a closed container and use them within a few days. For longer storage, freeze the juice or concentrate in an ice-cube tray, then move the cubes to a sealed bag. Frozen cubes are easy to measure and thaw only what a recipe needs. Discard any juice that smells sour or fermented, or that shows mold.

How to Make Pandan Juice for Cake

For cake, make pandan juice as strong as possible, or use the concentrated extract, because extra water can weaken a delicate batter and dilute the color and aroma. The classic example is pandan chiffon cake, a tall, airy sponge popular across Southeast Asia, including Thailand.

• Use juice as part of the liquid. Many pandan cake recipes replace some or all of the water or milk with pandan juice. Keep the recipe's total liquid the same rather than adding juice on top of it.
• Use concentrate for stronger results. Concentrated extract gives a deeper color and aroma in a smaller volume, which helps light batters such as chiffon keep their structure.
• Combine with coconut milk. Pandan and coconut are a classic Thai pairing. Coconut milk adds richness that makes the pandan aroma feel rounder.
• Expect a natural color. A cake colored only with fresh pandan juice turns a soft, sage or olive green after baking, not the vivid lime green of bakery cakes. Those bright cakes usually rely on commercial paste with added coloring.

Tips for Better Homemade Pandan Juice

• Choose fresh, glossy leaves. Dark, shiny, firm leaves give the most aroma. Yellowed or dry leaves give weak, dull-tasting juice.
• Avoid the tough white base. It adds fiber and can make the juice taste bitter.
• Keep water low. You can always dilute strong juice, but you cannot easily strengthen weak juice without making a concentrate.
• Keep it cold. Heat and long exposure to air can turn the juice brownish and fade its aroma, so refrigerate it promptly.
• Use the leftover leaf pulp. The squeezed pulp still holds some fragrance. You can simmer it briefly in water or coconut milk for a lightly scented drink, then strain it again.

What Can You Use Instead of Fresh Pandan Juice?

Frozen pandan leaves are the closest substitute for fresh leaves. Bottled pandan extract, essence or paste is the most convenient alternative, though its flavor and color differ from homemade juice.

When you can find pandan leaves fresh or frozen, homemade pandan juice and concentrated extract give the most natural color and the most authentic fragrance for Thai desserts and pandan cakes.
