Palm sugar and brown sugar in Thai cooking
Palm sugar vs brown sugar: how they differ in source, taste, texture and use in Thai cooking, where white sugar fits, and what to expect when you substitute.
Contents
The short answer
Palm sugar and brown sugar are different ingredients, and they taste different. The main distinction is what they are made from and how they are processed. Brown sugar usually comes from sugarcane or sugar beets and keeps some of its molasses. Palm sugar comes from palms and is described as a raw, or unrefined, sugar. In cooking, brown sugar gives a deeper, moister, caramel-like result. Palm sugar is prized for a more complex flavor and a distinctive aroma that cooks of Thai and other Asian dishes look for.
How the flavors compare
Brown sugar's flavor comes from the molasses it retains, which is why it is associated with a caramel-like depth. Palm sugar is described as more complex, and it carries a strong, specific scent. That aroma is a strength in dishes built around it, but it can work against you elsewhere. In one Thai food community discussion, a commenter said palm sugar is used only in specific sweets because its scent can clash with other flavors in a dish. Treat that as a cook's observation, not a universal rule.
Form and texture
Brown sugar is granulated, like white sugar. It ranges from light to dark brown and is usually moist. Descriptions of palm sugar's form differ between sources. One contrasts palm sugar with granulated brown sugar. Another says the two are quite similar in color and consistency but notes that brown sugar holds noticeably more moisture than palm sugar. The safest takeaway is that the two may look alike, but brown sugar is the moister of the two.
Where white sugar fits
White sugar is the refined option of the three. Like brown sugar, it is granulated. Brown sugar differs from it by keeping some molasses. Palm sugar sits further from both as an unrefined sugar from a different plant source, and Thai sources present it as a more flavorful alternative to refined sugar.

Can you use palm sugar instead of brown sugar?
Either one will sweeten a dish, but they are not interchangeable in result. Choose brown sugar when you want a deeper, moister, caramel-like outcome. Choose palm sugar when a recipe depends on its authentic, complex flavor, as many Thai and other Asian recipes do. When swapping, keep two differences in mind. Brown sugar holds more moisture, which may change the texture of the finished dish. Palm sugar's pronounced aroma may stand out more than you expect, especially in dishes with many competing flavors.
