Japanese Royal Milk Tea
Japanese royal milk tea simmers black tea directly in milk for a rich, creamy cup. Leaf choice, the water-then-milk method and how to avoid a skin.
Before you start
Royal milk tea is the Japanese name for black tea brewed directly in milk rather than topped up with it. The leaves first open in a small amount of hot water, then milk is added to the pan and heated gently with the tea. The result is noticeably richer and rounder than an English-style cup with a splash of milk, with a creamy body and a caramel-like sweetness from the warmed milk.
Because milk dulls tea flavor, the choice of leaf and the heat matter. Strong, malty Assam or a robust breakfast blend holds up well; delicate teas get lost. Milk must stay just below a simmer: boiling it scalds the flavor and builds a thick skin. A short opening steep in water is the step that keeps the tea from tasting muted.
Ingredients
- 8 g (about 4 tsp loose) Assam or strong breakfast black tea — broken-leaf or CTC grade
- 100 ml (scant ½ cup) water
- 300 ml (1¼ cups) whole milk
- 10 to 20 g (2 to 4 tsp) granulated sugar — optional, to taste
Method
- Bring the water to a boil in a small saucepan. Add the tea leaves, turn off the heat, cover and let them open for 1 minute.
- Add the milk to the pan and set it over medium-low heat. Stir gently and occasionally with a spoon.
- Heat until the milk reaches about 85°C (185°F): steam rises steadily and small bubbles appear around the edge. This takes 3 to 5 minutes. Do not let it boil up.
- Turn off the heat, cover and steep for 2 to 3 minutes, depending on how strong you like it.
- Stir in the sugar if using, then strain into warmed cups, pressing gently on the leaves.
- Serve at once while the surface is smooth and before a skin forms.
Tips for success
- Broken-leaf or CTC tea extracts fast and strongly in milk. Large, whole leaves need a slightly longer steep.
- Stirring keeps milk from sticking to the bottom of the pan and catching.
- Warm the cups with hot water first. A milk tea cools quickly in cold porcelain.
- Taste before straining. If it is not strong enough, steep 1 more minute rather than adding more tea.
Substitutions
- Assam tea
- Ceylon makes a lighter, brighter cup. Darjeeling is too delicate for milk brewing. Earl Grey makes a perfumed version that some people like.
- Whole milk
- Oat milk works well and heats smoothly. Low-fat milk gives a thinner, less creamy cup. Soy milk may separate if overheated.
- Granulated sugar
- Honey, brown sugar or condensed milk all work. Condensed milk makes the drink richer and sweeter; add it after straining.
Variations
- Iced royal milk tea
- Make it slightly stronger with 10 g of tea, sweeten it while hot, then chill and pour over ice.
- Royal milk tea with spices
- Add a cinnamon stick or 2 crushed cardamom pods with the tea leaves.
Troubleshooting
- The tea tastes milky with little tea flavor
- The leaves were not opened in water first, or the tea was too delicate. Always start with the short water steep, and use a strong black tea.
- A thick skin formed on top
- The milk was overheated. Keep it below a simmer and stir while it heats.
- The milk tastes cooked or burnt
- It boiled or stuck to the pan. Use lower heat and stir more often.
Storage
Royal milk tea is best served immediately. Leftovers can be refrigerated in a covered container for 1 day and gently reheated, but a skin will form. Do not leave milk tea at room temperature for more than 2 hours.
Safety notes
Black tea contains caffeine. The FDA cites 400 mg per day as an amount not generally associated with negative effects for most healthy adults.
