How To Make Sour Milk

    If you go to the refrigerator and see the milk is sour, that’s typically negative. However, it can be a useful ingredient in a wide range of desserts and baked goods. It isn’t a good idea to consume milk that’s spoiled, however, so knowing how to sour your own milk will definitely be useful. When you mix a tiny bit of acid into regular milk, you can thicken it and make sure that it tastes tangy. You could even use the same method using a can of sweetened condensed, but you’ll need a bit of water to reduce the amount.

    What is the difference between spoilt milk and sour milk?

    Sour milk is raw milk that has been stored in room (or warmer) conditions for some certain amount of time until it gets slightly thicker and develops an acrid taste.

    It takes about one hour for it to begin. However, it may happen faster in a warm area or an area inside the kitchen.

    The term “soiled” refers to milk that has become spoiled and isn’t suitable for consumption.

    Spoiled milk could be extremely risky as it’s full of different kinds of bacteria that are harmful to the human digestive system. Milk that has been spoilt will not be able to have the pleasantly sour, fermented taste of clabbered or soured milk, but it can smell and taste disgusting.

    Your nose will inform you that milk is not good.

    Be aware that pathogens that pose a risk can thrive and multiply in all milk regardless of whether it smells or taste “off” as well. This is also true for unpasteurized and pasteurized milk alike.


    Also, there is Buttermilk, which is the leftover liquid from the process of making butter. It is made of sugary cream, or even cream left to be cultured (i.e make ferment) at the temperature of a room for around 24 hours.

    I will explain the procedure in detail here in which I show the art of making cultured butter, also known as Sweet Cream Butter.

    Sometimes, Buttermilk is referred to as Whey, too.

    Sweet and Acid Whey

    There is also Whey which is the leftover liquid from the cheese-making process.

    There are two kinds of Whey. One is acid Whey that results from the making of vegetarian cheeses like in my paneer recipe.

    The other is sweet Whey, which is a leftover from the cheeses with renneted. Rennet is an enzyme that can be found in the stomach of a calf.

    Whey is a rich source of protein.

    How to Make Sour Milk

    Many baking recipes use Sour milk, which is sometimes used to substitute for Buttermilk. Sour milk and Buttermilk are slightly acidic and are needed to counterbalance the acidity of the ingredients of the recipe. The milk that is in sourness on its own has gone bad and is not safe to use. In order to make one cup (250 milliliters) of sweetened sour milk for baking, make use of 1 tablespoon (15 milliliters) of lemon or vinegar and enough milk to make 1 cup (250 milliliters). Mix and let it sit for 5 minutes prior to using.
    What is the best way to make Sour Milk substitute for Buttermilk
    Do you need Sour Milk to create an idea? It’s a breeze to make and often used in place of Buttermilk. While it’s not as exact as Buttermilk, it’s like it and has the acidity that some recipes could require, particularly for baking.
    Recipes that require baking powder or baking soda that require Buttermilk or sour milk require the acidity to increase.


    • 1 tbsp white vinegar or lemon juice
    • One cup milk one teaspoon less, follow the instructions


    For making exactly 1 cup of sour milk, add 1 teaspoon of vinegar or 1 teaspoon of juice from a lemon into a measuring cup. Fill the cup with milk up at the one-cup mark. Give it a good stir.

    • You can make sour milk using reduced-fat, fat-free, as well as whole milk.
    • Utilize either white or lemon juice that has 5 percent acidity. It has a neutral taste and is non-colorless. If you are in a pinch, you can make use of white wine vinegar. Other vinegar is not appropriate because it gives an unpleasant flavor and color to the sour milk.
    • The juice of the lemon can be squeezed fresh or stored in a bottle. If you are using fresh juice lemon juice, strain it through a strainer to remove seeds and pulp.
    • Certain recipes for sour milk include the acidifier as cream of tartar. Although it serves as a leavening agent, cream of tartar doesn’t provide the typical tangy flavor you would expect from sour milk.
    • It is recommended to start by using milk that is still at room temperature. If you are bringing the milk straight from the refrigerator, you will require extra time. The amount of time needed depends on the temperature of the surrounding air as well as the liquid will begin to thicken and continue to curdle when you give it longer. However, it’s not recommended to allow the milk to sit in the refrigerator for long periods of time or over a period of time for it to turn sour as it was in the past. The milk could be sour and then spoiled.
    • The acidification process of milk stops the development of bacteria that cause harm. Even if you change the milk into sour, the date of sale on the bottle is an indication of when to utilize it. In general, the product that is soured must be consumed within a week from the sell-by date.
