Korean citron tea, known as yuja cha, is a thick citrus preserve made from sliced yuja fruit cured in honey or sugar. While it is Korea’s favorite winter remedy for a scratchy throat, locals know it is far more than medicine. From fizzy summer sodas to savory meat glazes, a good jar of yuja marmalade is one of the most hardworking staples in a Korean kitchen.
What Korean Citron Tea Actually Is
If you order citron tea expecting a dried tea bag, you are in for a pleasant surprise. Yuja cha is brewed by stirring a spoonful of yuja-cheong—a glossy, golden marmalade made of thinly sliced citrus and sweetener—directly into hot water.
The fruit itself, yuja (known as yuzu in Japan), looks like a small, bumpy yellow grapefruit. It is far too sour and seeded to eat raw, but its thick rind contains an incredible amount of fragrant, floral oils that perfume an entire room the second you crack open the jar.
Because there are no actual tea leaves involved, yuja cha is naturally caffeine-free. You can drink a steaming mug right before bed without worrying about your sleep schedule.
Late-Night Runway Fittings and a Jar of Gold
When I worked as a fashion designer in Manhattan’s Garment District, winter was always our most brutal season. We had late-night fittings right before runway shows, pinned against drafty studio windows with rolls of wool fabric stacked to the ceiling.
Everyone ran on burnt office drip coffee, which only left us jittery and dehydrated by midnight.
Eat the Peel: Three Local Secrets to Drinking It Right
Do you leave the fruit peel sitting at the bottom of your mug when you finish? If so, you are missing out on the very best part of the drink.
- Chew the candied rinds: The thin slivers of yuja peel at the bottom have soaked in honey or sugar for weeks. They become soft, chewy, and intensely aromatic, so grab a spoon and eat them all.
- Order it iced as “Yuja Ade”: Korean cafes do not pack away the citron jars when spring arrives. They shake a couple of spoonfuls of yuja marmalade with sparkling water and plenty of ice for a refreshing summer soda.
- Watch the water temperature: Boiling water straight from the stove can scorch the delicate citrus aroma and leave a bitter aftertaste. Let your kettle sit for two minutes before pouring so the floral top notes stay bright.
How to Use Yuja Cheong Beyond the Mug
Think of yuja marmalade as a culinary secret weapon rather than just a drink base. Because it balances intense citrus acidity with thick sweetness, it works magic in both sweet and savory cooking.
Whisk a spoonful of yuja preserve into extra virgin olive oil, a splash of vinegar, and a pinch of salt for an instant citrus vinaigrette. It cuts right through bitter greens like kale or chicory with zero effort.
You can also brush it over grilled salmon or chicken during the last two minutes of cooking. The sugars caramelize into a glossy, fragrant lacquer that tastes like a professional restaurant glaze.
How Yuja Compares to Other Traditional Korean Preserved Teas
Walk down the tea aisle of any Korean supermarket, and you will see an entire wall of heavy glass jars. Here is how yuja stacks up against the other classic fruit preserves found in Korean homes:
It keeps for months once opened, as long as you always use a clean, dry spoon to scoop it out.
FAQ
Q. Does Korean citron tea contain caffeine?
A. No, authentic yuja cha is made purely from citrus fruit, peel, and honey or sugar. It contains no actual tea leaves (*Camellia sinensis*), making it entirely caffeine-free.
Q. How long does a jar of yuja preserve last after opening?
A. Because the high sugar content acts as a natural preservative, an opened jar will easily keep in the refrigerator for 6 to 12 months. Just make sure moisture never enters the jar from a used spoon.
Q. Can I use hot tap water to make it?
A. Hot tap water usually will not dissolve the thick marmalade smoothly. Heat your water to about 175°F to 185°F (80°C to 85°C) so the rind softens and releases its fragrant oils.
Q. Is yuja the same fruit as a Meyer lemon?
A. Not quite. While both are sweet-tart citrus fruits, yuja (yuzu) has a much thicker, bumpier peel with a unique, perfume-like aroma that smells like a cross between a mandarin orange, a grapefruit, and lime. Korean citron tea is a marmalade-style preserve (*yuja-cheong*) that stirs directly into hot or cold water. The fragrant, chewy citrus peel at the bottom of the cup is completely edible and contains the best flavor. A single jar doubles as a soothing caffeine-free winter tea, a fizzy summer cooler, and a bright citrus glaze.
