Chai Brewing Guide · Kadak Chai Recipe · Step-by-Step Method
Every Indian family has their chai recipe. And almost every Indian family argues about it. Too much water makes it pale and weak. Too much milk makes it flat and heavy. Brew it too long and it turns bitter. Don’t brew it long enough and it tastes like warm colored water.
The difference between a forgettable cup and a proper kadak chai — the kind that fills the kitchen with aroma, looks deep copper in the glass, and wakes you up properly — almost always comes down to two things: the ratio and the method.
Here’s exactly what the best chai wallahs know that most home cooks don’t.
First — the ratio that determines everything
01
Three Ratios, Three Very Different Cups
There is no single “correct” water-to-milk ratio — it depends on how strong and how creamy you like your chai. But each ratio produces a very different result, and knowing which one to use is the first step to consistent, great chai.
3:1
Light Chai
3 parts water, 1 part milk. More tea flavor, lighter body. Good for those who prefer a strong but less creamy cup.
2:1
Classic Kadak
2 parts water, 1 part milk. Deep color, full flavor, lighter on creaminess. The popular dhaba ratio.
1:1 ✓
TEA SENSE Kadak
Equal parts — 90 ml water + 90 ml milk. Rich color, creamy body, full flavor. The TEA SENSE recommended ratio for the perfect cup.
The Kadak Sweet Spot For a standard cup of kadak chai at home, use 1:1 — 90 ml water and 90 ml milk per cup. Equal parts water and milk gives you the perfect balance of strong tea flavor and creamy body — rich copper color in the cup, full-bodied taste, and just the right thickness for a satisfying kadak chai.
The reason most homemade chai disappoints is that people pour in too much milk — either by habit or to soften the bitterness of low-quality tea dust. More milk literally dilutes the color compounds and washes out the flavor. The fix is better tea, not more milk.
The boiling method — the answer to “what is the best way to boil Indian chai?”
02
The Two-Stage Method: How the Best Chai Is Actually Made
Most people make chai in one stage — dump everything in a pot and boil it together. The result is always slightly off: either the color is weak, or the milk is overcooked, or the spices haven’t had a chance to bloom properly.
The two-stage method fixes all of this. Here’s the exact process:
1
Pour water and add tea leaves — boil for 1 minute Pour 90 ml of water into the pan and place on medium-high heat. Once it starts to boil, add 1 level teaspoon of TEA SENSE Gold CTC. Let it boil hard for exactly 1 minute. This is where the deep copper color builds — the theaflavin compounds in quality CTC extract best in boiling water before any milk enters the picture.
2
Add milk and boil to the brim once Pour in 90 ml of milk (1:1 ratio with water). Turn heat to medium-high. Watch the pan closely — let the chai rise all the way to the brim, then pull the pan off the heat or reduce immediately before it overflows. This first rise blends the tea and milk together and starts building creaminess.
3
Add ginger and boil to the brim once Add freshly grated or crushed ginger to taste. Return to heat and let the chai rise to the brim one more time, then pull back. Adding ginger at this stage — after milk is in — releases its warmth and sharpness into a fully blended base, giving a clean, balanced ginger hit rather than an overpowering raw bite.
4
Add sugar and boil to the brim 1–2 times Add sugar directly to the pan. Return to heat and let the chai rise to the brim once — pull back, then bring it to the brim a second time if you want a richer, more integrated sweetness. This fully dissolves the sugar and melds every element together into one cohesive cup.
5
Strain and serve immediately Pour through a fine strainer directly into your cup. Serve at once — chai loses its aroma and that fresh “just-made” quality within minutes of leaving the heat. The cup should be deep copper-amber in color, creamy, and steaming hot.
The Rule That Matters Most Tea powder always goes into boiling water first — never into cold water, never into milk, never all together at once. Boiling water is the only medium that properly extracts the color compounds from CTC tea. If you skip this step, no amount of milk ratio adjustment will give you the deep kadak color you’re looking for.

Why Your Chai Comes Out Pale, Bitter, or Flat — and the Fix
| The Problem |
The Cause |
The Fix |
| Pale, washed-out color |
Tea added to cold water or milk, or too little brew time |
Always add tea to boiling water first; boil for 1 full minute before adding milk |
| Weak, watery flavor |
Tea brewed for less than 1 minute, or too much water |
Boil tea in water for a full minute before adding milk |
| Bitter, harsh taste |
Boiled for too long (8+ minutes) or over-steeped |
Keep total brew time under 6 minutes; do the double-boil method |
| Flat, no aroma |
Spices added too late or not boiled in water first |
Boil spices in water for 2 minutes before adding tea |
| Still pale despite lots of tea |
Dust-grade tea that has lost potency |
Switch to fresh BOP-grade CTC; 1 spoon should be enough |
“Kadak chai isn’t about using more tea or more milk — it’s about doing things in the right order at the right time.”
04
Does the Type of Milk Make a Difference? Yes. Here’s How.
Most people think milk is milk. But the fat content in your milk directly affects how your chai looks, tastes, and feels in the cup — and it interacts with the water ratio in ways that matter.
Best Milk for Kadak Chai Full-fat whole milk (6% fat or above): Richest color, creamiest body, best mouthfeel. The fat molecules emulsify with the tea to create that thick, velvety texture.
Toned milk (3% fat): The most common choice for everyday kadak chai. Works perfectly with the 2:1 ratio. Gives good color and body without being too rich.
Skim or low-fat milk: Avoid for kadak chai. The lack of fat makes the chai thin and watery, and you end up adding more milk to compensate, which dilutes the color. A cycle that ends in pale, flat chai.
If your chai always looks pale and thin even with the right ratio, check your milk. Switching from toned to full-fat can transform the cup without changing a single thing in your method.
05
The Right Ratio Means Nothing Without the Right Tea
“You can have the perfect ratio and the perfect method — but if your tea powder is stale dust, your chai will still disappoint.”
Ratio and method are the foundation. But the ingredient that determines whether your chai goes from good to genuinely great is the quality of your CTC tea powder.

Your Questions, Answered
What is the best way to boil Indian chai?
The best way is the TEA SENSE method: pour water into the pan, add tea leaves and boil for 1 minute to build deep color. Add milk and boil to the brim once. Add ginger and boil to the brim once. Add sugar and boil to the brim 1–2 times. Strain and serve immediately. Never dump everything in together — the order is what makes the difference between pale chai and perfect kadak.
What is the correct water to milk ratio for kadak chai?
TEA SENSE recommends 1:1 — 90 ml water and 90 ml milk per cup. Equal parts gives the perfect balance of strong tea flavor and creamy body. For a lighter cup use 2:1 (more water, less milk). For very thick doodh patti use 1:2. The 1:1 ratio with premium BOP-grade CTC gives you that deep copper color and full kadak flavor in one satisfying cup.
Why is my chai coming out pale even with enough tea powder?
Most likely causes: adding tea to cold water or milk instead of boiling water first, not boiling the tea in water for a full minute, or using stale dust-grade tea. Fix: always start with water, add tea and boil 1 minute, then add milk and bring to the brim. Follow the sequence — water → tea → boil → milk brim → ginger brim → sugar brim. The order is everything.
Does the order of adding milk and tea matter?
Yes, significantly. Tea powder should always go into boiling water first. Boiling water extracts color compounds (theaflavins) far more effectively than milk does. If you add milk first, you steep tea in a lower-temperature, fat-coated liquid and never get proper color extraction — resulting in pale, underpowered chai no matter how much tea powder you use.
How long should chai be boiled after adding milk?
After adding milk, bring the chai to the brim once — let it rise high then pull back. Then add ginger and bring to the brim once more. Then add sugar and bring to the brim 1–2 times. Each “brim boil” blends the ingredients, develops creaminess, and deepens the flavor. Boiling each addition to the brim is the method that gives chai wallahs their consistently perfect cup.
What type of milk makes the best kadak chai?
Full-fat whole milk gives the richest, creamiest chai with the best color and body. Toned milk (3% fat) works well for everyday kadak chai. Avoid skim or low-fat milk — the lack of fat makes chai thin and watery, and you end up adding more milk to compensate, which dilutes the color and creates a cycle of pale, flat chai.
