Korean yuja tea, or yuja-cha, is a fragrant drink made by stirring yuja-cheong—sliced Korean yuja preserved with sugar—into hot water. This recipe makes a refrigerated citrus concentrate ahead of time, then shows how to turn it into a balanced cup with plenty of peel, juice, and aroma.
Ingredients
- 1 lb (454 g) fresh Korean yuja, or fresh yuzu if available
- 2 cups (400 g) granulated sugar
- 10 cups (2.4 L) hot water, for serving
- 10 thin slices (about 2 oz / 55 g total) fresh yuja or lemon, optional garnish
The fruit and sugar make the yuja-cheong, the sweet citrus base for the drink. The hot water and optional garnish are used when serving, not when preparing the refrigerated concentrate. A kitchen scale is useful because fruit size and juiciness vary; the quantities here are a practical starting point rather than a requirement to use every drop of water or concentrate at once.
Instructions
- Wash and dry the fruit, about 5 minutes. Rinse the yuja under cool running water and scrub the textured skin gently to remove dirt. Dry it very thoroughly with a clean towel. If the fruit has a waxy coating, take extra care to scrub and rinse it. Water left on the peel or in the jar can dilute the syrup and make the mixture spoil sooner.
- Prepare a clean jar. Choose a clean, dry, heat-safe glass jar with enough room for the fruit and sugar, ideally about 1 quart (946 ml). Wash it with hot, soapy water, rinse, and let it dry completely. This is a refrigerated recipe, not a canning method; do not plan to store the jar at room temperature.
- Slice and seed the yuja, about 15–18 minutes. Cut off and discard the stem ends, then slice the fruit crosswise as thinly as you can, aiming for slices around ⅛ inch (3 mm). Remove visible seeds as you go because they can add bitterness. Keep the fragrant peel, flesh, juice, and the soft membranes between the segments. If a slice has an unusually thick, tough central core, trim away just that portion rather than removing all the peel.
- Mix with the sugar, about 2 minutes. Put the slices and any juice on the cutting board into a clean bowl. Add the sugar and toss gently until the slices are coated and the sugar begins to look damp. Spoon the mixture into the jar, pressing lightly with a clean spoon to reduce large air gaps. Leave a little headspace at the top and wipe the rim clean before closing the lid.
- Refrigerate for 24 hours. Put the closed jar straight into the refrigerator at 40°F (4°C) or colder. During the first day, the sugar draws liquid from the fruit and starts to form a fragrant syrup. If you happen to open the refrigerator, you can turn the jar gently once, but there is no need to shake it or leave it on the counter. The concentrate is easiest to use once the sugar has mostly dissolved and the slices look glossy.
- Make each cup, about 3 minutes. For one serving, spoon 2 tablespoons (30 g) of yuja-cheong, including a few slices, into a mug. Add 1 cup (240 ml) hot water and stir until the syrup disperses. Let it stand for about 3 minutes so the citrus flavor infuses the water, then taste. Add another spoonful of concentrate for a sweeter, more intense cup, or more hot water for a lighter one. Garnish with a fresh citrus slice if you like.
Tips
- Dry the fruit completely. The syrup depends on sugar and citrus juices, not added water. Water droplets on the peel, cutting board, or jar can thin the mixture and make it less dependable in storage. If you wash the fruit ahead, leave time for it to air-dry before slicing.
- Keep the peel, remove the seeds. Yuja peel carries much of the distinctive floral-citrus fragrance, so discard only the stem ends and seeds. Very thin slices make the fruit pleasant to eat from the cup and help the sugar draw out juice. If you find peel too chewy, make the slices thinner or simply leave them in the mug while drinking.
- Adjust sweetness by the spoonful. Start with 2 tablespoons of concentrate per cup, then tune the ratio to your taste and the strength of the fruit. If the cup tastes overly sweet, add hot water or a little lemon juice. Avoid adding extra sugar to the jar just to correct an individual cup.
- Use a clean utensil every time. Take concentrate from the jar with a clean, dry spoon and return it to the refrigerator promptly. Do not dip a used spoon into the jar. If you notice mold, bubbling, an alcoholic smell, or an unusual change in texture, discard the concentrate rather than tasting it.
Serving Suggestions
Serve yuja tea hot in small mugs or teacups, with a spoon in the cup so guests can stir in the syrup as they drink. The citrus slices are edible, though the peel may be pleasantly chewy rather than tender. For a less sweet drink, use one tablespoon of yuja-cheong in a larger mug and top up with hot water. For a stronger cup, use two tablespoons or allow the fruit to steep a few minutes longer.
It also works well as a bright finish after a meal, alongside plain cookies, rice cakes, or lightly sweet pastries. If serving several people, put the concentrate in a small serving bowl and let everyone add it to their own hot water; that makes it easy to accommodate different sweetness preferences. Keep the jar of concentrate chilled between rounds rather than leaving it out for the whole gathering.
For an iced version, stir 2 tablespoons (30 g) of concentrate into 2 tablespoons (30 ml) of warm water to loosen it, then add 1 cup (240 ml) cold water and a glassful of ice. Stir well before drinking because the syrup is denser than cold water. A squeeze of fresh lemon can sharpen a particularly sweet batch, but taste the drink before adding it.
Variations
Use yuzu or a citrus blend. Fresh Korean yuja can be difficult to find outside Korean grocery stores and markets. Fresh yuzu is the closest practical substitute and gives a similarly perfumed, tart result. If neither is available, use a mixture of thin-skinned lemon and orange: for this recipe, use about 10 oz (285 g) lemon and 6 oz (170 g) orange to make 1 lb (454 g) total fruit. The result is still fragrant and pleasant, but it will taste more familiar and less floral than yuja.
Make a ginger version in the cup. Add 2 or 3 thin slices of fresh ginger to a mug before pouring in the hot water, or steep them in the water for a few minutes first. Ginger contributes a warm, peppery note that changes the drink’s flavor without changing how the concentrate is stored. Remove the ginger before serving if you prefer a gentler taste.
Add a little honey when serving. If you want a rounder sweetness, stir up to 1 teaspoon (7 g) honey into an individual cup. Honey is optional and is not needed in the jar; adding it to one serving lets you adjust the flavor without changing the stored concentrate. You can also use a small amount of another sweetener, keeping in mind that each one will affect the taste.
Serve it chilled or sparkling. Dissolve the concentrate in a little warm water first, then add cold still or sparkling water and ice. Use a tall glass and stir gently if using sparkling water so it does not lose its bubbles. Begin with 1 tablespoon (15 g) concentrate per cup, then add more to taste; a cold drink can seem less sweet than a hot one.
Storage and Reheating
Refrigerate the yuja-cheong promptly, within 2 hours of preparing it, and keep it at 40°F (4°C) or colder. Use it within 2 weeks for best quality, always taking it out with a clean, dry utensil. The sugar helps draw out the fruit’s juice, but this homemade mixture is not shelf-stable and must not be stored in a cupboard or treated as a canned preserve. Do not rely on the lid or the amount of sugar to make it safe at room temperature.
For longer storage, freeze the concentrate in a freezer-safe container, leaving room for expansion, for up to 3 months. You can also freeze small portions in an ice-cube tray and transfer the solid cubes to a freezer bag. Thaw the amount you need in the refrigerator, not on the counter, and do not return a thawed portion to the main jar.
Prepared tea is best enjoyed right after mixing. If you have leftover brewed tea, cool it and refrigerate it within 2 hours in a covered container; use it within 3–4 days. Reheat gently in a saucepan or microwave until steaming, then stir well. Avoid boiling it for a long time, which can flatten the fresh citrus aroma. If the tea contains citrus slices, remove them before storing if you prefer a cleaner flavor.
Frequently Asked Questions
Is yuja tea made with tea leaves?
Usually, no. Korean yuja-cha is a fruit drink made by mixing yuja-cheong with hot water, so it does not need black, green, or herbal tea leaves. You can steep a tea bag separately and add a little yuja-cheong if you want a tea-based variation, but that will taste different from the simple citrus drink.
Can I make this with bottled yuja-cheong?
Yes. Stir 1–2 tablespoons (15–30 g) of ready-made yuja-cheong into 1 cup (240 ml) hot water, then adjust the strength to taste. Follow the product’s storage directions after opening; this homemade recipe’s two-week guidance does not automatically apply to a commercial product.
Why is my yuja tea bitter?
Common causes include leaving seeds in the slices, using fruit with a particularly bitter pith, or adding too much peel-heavy concentrate to one cup. Remove visible seeds carefully, slice thinly, and begin with a smaller spoonful of syrup. A little lemon juice or extra hot water can balance a cup that is already made, but it cannot remove bitterness from the jar.
Can I use less sugar?
You can reduce the sugar, but it will produce a looser, more tart mixture and may not keep as well. Since this recipe relies on refrigeration rather than a tested canning process, keep any reduced-sugar version refrigerated, use it within a few days, and freeze portions you will not use soon. Do not leave it at room temperature to compensate for less sugar.
Do I have to wait a full day before drinking it?
The 24-hour rest gives the sugar time to pull juice from the fruit and form a spoonable syrup. You can make a quick cup by steeping a few thin slices of fresh yuja with sugar in hot water, but it will be lighter and less rounded than tea made with the rested concentrate. Keep the jar refrigerated even if you serve a quick cup first.
Can I use the fruit slices after I finish the syrup?
Yes, if they have remained properly refrigerated and show no signs of spoilage. Add a slice to a cup, chop a little into plain yogurt or oatmeal, or discard it if the peel is too chewy for your preference. The slices are quite sweet after sitting in the syrup, so taste a small piece before using a larger amount.
