How to Prepare Pandan Leaves for Cooking

Pandan leaves are prepared by washing, trimming, and often knotting them before use. For frozen leaves, thaw them first. This releases their grassy, vanilla-like aroma into dishes like rice, custards, and wrapped chicken.

What Are Pandan Leaves?

Pandan leaves are long, blade-like leaves from the screwpine tree, widely used in Southeast Asian cooking. They're deep green, about 1–2 inches wide, and can grow over a foot long. Fresh leaves are glossy and pliable, with a sweet, floral fragrance reminiscent of vanilla, grass, and jasmine. Frozen leaves are darker, slightly limp after thawing, but still aromatic. Pandan is sometimes called "vanilla of the East" because it imparts a similar sweet aroma, but it's not related to vanilla. Unlike banana leaves, which are used mainly as wrappers, pandan leaves are used primarily for their flavor and color—they can tint foods a soft green.

Preparing Fresh Pandan Leaves

Fresh pandan leaves need cleaning, trimming, and often knotting to release their aroma.

Washing

Rinse each leaf under cool running water, rubbing gently to remove dirt or residue. Pat dry with a clean towel. If leaves are dusty, soak them in a bowl of water for a few minutes, then rinse.

Trimming

Use a sharp knife or scissors to cut off the tough base where the leaf was attached to the plant—usually the bottom inch. Also trim any brown tips or edges. The remaining leaf is tender and flavorful.

Knotted Pandan Leaves

Knotting pandan leaves is a traditional technique that bruises the leaf, releasing more essential oils into the dish. To knot, take a leaf and tie it into a simple overhand knot, as you would with a piece of string. If the leaf is long, you can tie two or three loose knots along its length, or fold it into a bundle and tie it around itself. Knotted leaves are commonly added to rice cookers, curries, or desserts where they simmer and infuse their flavor, then are removed before serving.

Preparing Frozen Pandan Leaves

Frozen pandan leaves are convenient and retain most of their aroma, but they need proper thawing.

Thawing

Remove the desired number of leaves from the freezer and let them thaw at room temperature for 10–15 minutes. They will become pliable but may feel slightly soft. Do not thaw in hot water, as this can leach out flavor. If you're in a hurry, you can run them briefly under cool water.

After Thawing

Once thawed, treat them like fresh leaves: rinse, trim, and knot as needed. Frozen leaves may be a bit more fragile, so handle gently when tying knots.

How to Use Prepared Pandan Leaves

Prepared pandan leaves are used for aromatic infusion, most often by simmering them in liquids or steaming them with foods.

Aromatic Infusion

Add knotted pandan leaves to a pot of rice while it cooks; the rice will absorb a subtle, sweet fragrance. Steep them in warm coconut milk for desserts like khanom chan (layered pandan cake) or bua loy (rice dumplings in coconut milk). For a stronger flavor, blend chopped pandan leaves with a little water and strain to get pandan juice, which can be used to color and flavor cakes and drinks.

Wrapping

Pandan leaves can also be used as wrappers for steaming or frying, similar to banana leaves but smaller. A classic Thai dish is gai hor bai toey (pandan-wrapped chicken), where marinated chicken pieces are wrapped in pandan leaves and deep-fried. The leaf imparts aroma and keeps the meat moist.

Comparison: Fresh vs. Frozen Pandan Leaves

Both fresh and frozen leaves work well, but there are differences in texture and convenience.

Substitutes for Pandan Leaves

If you can't find pandan leaves, vanilla extract or vanilla bean can be used as a flavor substitute, especially in desserts. However, vanilla lacks the grassy, herbal notes and the green color pandan provides. For coloring, a drop of green food coloring can mimic the hue, but not the taste. Some cooks use a combination of vanilla and a small amount of matcha or pandan paste. Pandan paste, sold in jars, is a concentrated alternative but often contains additional sweeteners and colorants.

Storing Prepared Pandan Leaves

Fresh pandan leaves can be wrapped in a damp paper towel and stored in a plastic bag in the refrigerator for up to a week. For longer storage, freeze them in an airtight bag for up to six months. Prepared knotted leaves should be used immediately, as bruising accelerates wilting.
