Chai Ratio Cheat Sheet: Water, Milk, Tea and Sugar

Your chai tastes watery on Monday and like boiled bark on Tuesday, and you used the same spoon both days. The problem is rarely the tea. It is the ratio, and most of us eyeball it until the cup tells us we were wrong.

This is a measuring sheet, not a lecture on which chai is more authentic. If you want the difference in style, our post on karak chai versus doodh patti covers that. Here you get numbers to copy.

The numbers from our three chai recipes

All three use strong loose black tea, which our recipes call chai patti, and sugar added with the milk.

<!-- VERIFY: ingredient amounts were read from the recipe data by position; masala chai water of 300 ml comes from step 2, milk 300 ml from the ingredient list. Confirm on the live pages. -->

Notice how different they are. Doodh patti uses 2 tablespoons of tea for 500 ml of milk. Masala chai uses only 2 teaspoons for roughly the same total liquid, because the spices carry flavour.

Scale it down to one cup

Say you want a single serving of about 150 ml.

• Karak style: 1/2 tbsp tea (about 1 1/2 tsp), 1 cardamom pod, 100 ml water, 50 ml milk, 3/4 tbsp sugar. The result is about 2:1 water to milk, boiled hard.
• Doodh patti style: 1/2 tbsp tea, 1 cardamom pod, 250 ml milk, 1 tbsp sugar. This makes about a mug, not a small glass.
• Masala chai style: 1/2 tsp tea, 1 pod of cardamom, a thin slice of ginger, 75 ml water, 75 ml milk, 1/2 tbsp sugar.

For single cups, use a small pan. In a wide pan the liquid is shallow and it burns before it brews. One tea-spoon of tea is not many leaves, so the pan size matters.

<!-- VERIFY: one-cup scaling is simple arithmetic from the recipe rows and has not been tasted-tested. -->

Why the method matters as much as the ratio

The same tea and milk make two different drinks, depending on the order.

• Karak: boil water with cardamom for 2 minutes, add tea and boil hard for 3 minutes until the water is deep red-brown. Pour in the milk and sugar and boil hard again for about 5 minutes, letting it rise and fall a few times.
• Doodh patti: boil the milk with cardamom (about 5 minutes), add tea, then simmer about 4 minutes until it is deep reddish-brown. Add sugar, and simmer 1 more minute.
• Masala chai: simmer the spices in water for 4 minutes first, then tea for 2 minutes, then add milk and sugar and simmer 3 minutes on low.

Cooking tea in water first extracts colour and tannin without the milk fat softening it. Simmering it in milk gives a creamier, softer cup. If your karak is too bitter, it is usually the second boil that ran too long.

Fixing the cup you just made

• Weak and pale. Add a half tablespoon more tea next time, or boil the tea in water 1 minute longer before the milk. Do not just add more milk.
• Bitter or harsh. Too long after the milk went in, or too much tea. Cut the post-milk simmer to 2 or 3 minutes. Masala chai's own notes warn that a long boil after the milk turns it bitter.
• Thin. Too much water for your milk. Karak goes about 2:1 water to milk, so it is thin by design. If you want it creamier, move toward the doodh patti method.
• Too sweet. Start with 2 tbsp for 4 cups, taste, and add more. Sugar is the easiest thing to add later and the hardest to remove.
• Boils over. Watch the foam. When it reaches the rim, lower the heat. Our recipe tip says to lower the heat at once rather than lifting the pan on and off.

Tea leaves: what to buy

Our recipes say strong loose black tea, not tea bags, gives the deepest colour. In shops this usually means CTC tea (granules rolled for fast, strong brewing) or Assam. Delicate whole-leaf teas such as Darjeeling make a poor milk chai, because the flavour disappears under milk.

If you only have tea bags, use two bags per cup and boil a minute or so longer. It will be less red.

<!-- VERIFY: tea bag substitution (2 bags per cup) is a general rule of thumb, not from the recipe data. -->

Batch chai for guests

For six cups, multiply the karak recipe by 1.5: 3 tbsp of tea, 600 ml water, 300 ml milk, 4 1/2 tbsp sugar and 6 pods of cardamom. Use a pot big enough that the liquid is no more than half full, since it froths. Keep it hot on the lowest flame, and strain into a flask. Re-boiling chai that has stood for an hour makes it bitter.

A simple weekly plan

• Weekday mornings: doodh patti, because it is one pan and one milk.
• Cold evenings: masala chai, with ginger.
• Guests: karak, in small glasses.
• Summer: skip hot tea and make a lassi instead.

If you keep tea, sugar and cardamom in your Degchi pantry, the app will flag when they run low, so the morning pot never runs out of something.
