Rice Syrup

Rice syrup is primarily composed of maltose, maltotriose, and glucose — the sugar profile that results from enzymatic starch breakdown. Unlike sucrose (table sugar), these sugars create a less intense sweetness.

Rice syrup's sugar profile — primarily maltose and maltotriose rather than sucrose — is what gives it a gentler, less intense sweetness than refined sugar.

Traditional jocheong contains small amounts of B vitamins and minerals from the rice and barley malt, though these are present in modest quantities. The syrup has a moderate glycemic index — lower than pure glucose but higher than fructose.

Note that some commercially marketed "brown rice syrup" products have raised concerns about arsenic content, as rice can accumulate arsenic from soil and water. Quality sourcing and testing are important.

Rice syrup production in Korea and China dates back over a thousand years, originating from the discovery that malted grain enzymes could convert starch into sugar. Before sugar was widely available and affordable in East Asia, grain-based syrups were the primary sweetener.

Traditional jocheong is made by mixing cooked glutinous rice with barley malt powder, allowing the enzymes to break down starches, then straining and reducing the liquid into a thick syrup. This is a labor-intensive process that families once performed at home.

Before refined sugar was widely available in East Asia, grain-based syrups like jocheong were the primary sweetener — and many Korean cooks still prefer them today.

Modern mulyeot (often translated as corn syrup or starch syrup) is a lighter, less complex commercial version made from corn or sweet potato starch. While traditional jocheong has more depth and character, mulyeot is widely used in everyday Korean cooking for its neutral sweetness and glossy properties.

Use rice syrup as a glaze for braised and stir-fried dishes — add a tablespoon or two in the final minutes of cooking to create the characteristic Korean glossy sheen. It is essential in dishes like dakgalbi, tteokbokki, and braised short ribs.

Drizzle over hotteok (Korean sweet filled pancakes) or use as the binding syrup for gangjeong (puffed rice and nut clusters) and yakgwa (honey cookies). Mix into marinades where you want sweetness without graininess.

Rice syrup does what sugar cannot in Korean cooking — it adds sweetness with body, gloss, and depth. It creates the glossy sheen that distinguishes well-made Korean braised and glazed dishes.

Substitute for honey or corn syrup in most applications where a clean, malty sweetness and glossy texture are desired. In modern baking, rice syrup works as a liquid sweetener in granola bars, energy balls, and no-bake desserts.

Rice syrup is ready to use straight from the bottle. For easier pouring, warm the bottle briefly in hot water — cold rice syrup can be very thick and slow.

Jocheong vs. mulyeot: If a recipe calls for "jocheong" specifically, seek out the traditional barley-malt version from Korean grocery stores — it is darker, more complex, and significantly more flavorful than mulyeot. If it calls for "mulyeot" or "rice syrup" generally, either will work.

Store at room temperature. Rice syrup does not crystallize like honey and keeps indefinitely. If it becomes too thick, warm gently.
