How to Make Buttermilk at Home: Traditional, Quick & Baking Essentials
Let's talk about Buttermilk in Indian terms. The thin milky substitute we get after removing Butter from the Milk, Cream, or Curd is what we literally call buttermilk.
In terms of cuisine, it is cultured buttermilk; the ones you buy at stores are true cultured buttermilk, which would take about at least 10–12 hours to actively culture a buttermilk from milk. It is thinner than curd or yogurt, and what you need for the purpose is an active buttermilk culture, commonly known as stale buttermilk.
If you are churning out the butter from milk or cream, the byproduct is thin milk which has to be literally cultured using stale curd/buttermilk. Whereas, if you are churning out the butter from curd, then what we get is cultured buttermilk as such.

The Art of Homemade Butter and Buttermilk
 |
| Preparing and Churning Fresh Cream / Butter |
The buttermilk which I make at home is a byproduct I get while making Homemade Butter. The collected cream from the boiled milk is stored in the freezer until I get a lot, good enough to make butter at home.
Once I have a whole batch, I whip it up in my blender, adding a little bit of ice-cold water to the cream. I carefully whip the cream and cold water for a few minutes until the butter floats atop. Remove the butter, and what remains is the buttermilk.
The residual milk can be converted into true buttermilk by various methods:
Baking Substitute (Instant Method): Simply add an acidic agent, such as lemon juice or vinegar to the milk. This creates a quick-fix buttermilk that is ideal for leavening pancakes, cookies, and other baked goods.
Traditional Cultured Buttermilk: For superior taste, authentic flavour, and maximum nutritional value, it is best to culture the Milk using curd, yogurt, sour cream, or an active buttermilk starter. This traditional method unlocks the full probiotic potential and depth of flavour that instant methods cannot replicate.
Why Buttermilk is a Kitchen Essential
Buttermilk is one of the best drinks to beat the summer heat. The very nature of buttermilk, along with its probiotics, soothes your stomach and also helps to cut down the body heat. Buttermilk, otherwise called Moru, Mor, or Majjige in South Indian languages, is converted into flavoured drinks in the name of Neer Mor, Sambharam, Masala Majjige, or Chaas.
It is the same drink prepared with diluted curd or yogurt, or buttermilk flavoured with regional preferences.
Buttermilk is a versatile ingredient and is used in various dishes for its taste and flavour. Buttermilk provides the acidity required to neutralize the alkalinity of baking soda, creating the carbon dioxide bubbles that make cakes fluffy.

Freshly whipped Butter and Buttermilk from Milk Cream
Ingredients List
For the Traditional Cultured Method:
1 ltr Full Fat Milk
1–2 Tbspn Stale Curd or Buttermilk (Starter culture)
For the Quick Method:
1 Cup Fresh Curd/Yogurt
1 Cup Water (Adjust for consistency)

Method - Detailed Cooking Instructions
Step 1: The Traditional Cultured Method
Boil the milk and allow it to cool until it is lukewarm.
Add 2 tablespoons of stale curd or buttermilk and stir it well with a spoon or a spatula.
Cover the bowl and leave it aside in a warm place, such as on the kitchen counter next to the gas stove.
Leave it overnight, or at least five to six hours undisturbed, for the buttermilk to set.
Pro Tip: The setting time depends on your climate. In warmer weather, your cultured buttermilk will set much faster; keep an eye on it to prevent over-fermentation!

Step 2: The Quick Method (Diluted Curd)
Whisk the curd in a wide bowl, or whip it up in a blender.
Pour in the water and mix it thoroughly until you reach your preferred consistency.
Add a dash of salt to drink as-is, or add finely chopped herbs, ginger, and green chillies to create a spiced Neer Mor.
Pro Tip: For a perfectly frothy Sambharam, always use a blender to aerate the mixture. A quick 30-second whirl is enough to make the buttermilk light and refreshing.

Step 3: Instant Method for Baking
Add the lemon juice or vinegar to 1 cup of milk and give it a quick stir.
Let it sit at room temperature for about 10–15 minutes until it thickens slightly.
This acidified buttermilk is perfect for activating baking soda in recipes like cookies, biscuits, or pancakes.
Pro Tip: Don't worry if the milk looks slightly curdled or separated; that's exactly what you want! The acid has reacted with the milk proteins to create the perfect leavening agent.

Pro Tips and Notes
Starter Culture: Once you make your own, save a little from the previous batch to culture the next one. This allows you to continue the process for as long as you like.
Natural Cooling: If you want to replicate the traditional experience, store your buttermilk in an earthen pot to keep it naturally cool without a refrigerator.
Serving Suggestions
Serve buttermilk chilled with a pinch of salt.
For a traditional twist, blend it along with shallots, green chillies, curry leaves and ginger for the most refreshing Neer Mor or Sambharam as it's called in Tamil Nadu & Kerala.
Add roasted and powdered cumin seeds, black salt and normal salt for a spiced up North Indian Style Chaas.
Storage Suggestions
Refrigeration: Always keep your cultured buttermilk in the refrigerator to prevent it from becoming too sour. It stays good for up to 4 days.
Earthen Storage: If using an earthen pot, ensure it is cleaned thoroughly to prevent unwanted bacterial growth, and keep it in a cool, shaded area.
FAQ
What is the difference between store-bought and homemade cultured buttermilk?
- Store-bought is often commercially cultured, while homemade relies on your specific starter culture, providing unique probiotic benefits and a more authentic, traditional flavour profile.
Can I use the instant method for drinking?
- While the instant method (lemon/vinegar) is perfectly safe, it lacks the probiotic depth and flavour of traditionally cultured buttermilk, so it is best reserved for baking.
