The 5 Best Substitutes for Sour Milk

If you’re planning to bake or make a smoothie and discover that the milk has gone sour, don’t worry.

There are plenty of delicious alternatives you can use instead.

1 – Buttermilk

Buttermilk is a fermented dairy product made from low-fat or non-fat milk and cream.

Its distinguishing quality is its thickness, renowned for being easy to stir and pour with no wastage.

Buttermilk is known for its slightly tart flavor and smooth texture.

One of the many uses that buttermilk can be put to is as an ideal substitute for sour milk.

To create this substitute, take one tablespoon of lemon juice or white vinegar and add it to a cup of regular whole milk – let it sit for about 5 to 8 minutes until curdles form, and it starts to thicken; the result will taste close to traditional buttermilk.

2 – Make Your Own Sour Milk

Making sour milk is a simple and inexpensive way to add flavor to your baking or recipes.

It will also add a bit of texture since it is slightly thicker than normal milk.

To make your own sour milk, combine 1 cup of whole milk with one tablespoon of either lemon juice or white vinegar.

Cover tightly and allow the mixture to sit for 15 minutes at room temperature before stirring and using in recipes that call for sour milk.

This is a great alternative to having to buy expensive buttermilk for certain dishes.

You can also customize flavors by adding a pinch of garlic powder or cinnamon for savory and sweet influences, respectively.

3 – Milk Kefir

Milk kefir is an ancestral and health-promoting cultured milk drink made with living micro-organisms that convert milk sugars into beneficial acids.

It’s been part of traditional cuisine for centuries, stemming from the Russian Caucasus mountains.

Milk kefir tastes similar to yogurt and has a thick and creamy consistency, but it contains a different set of beneficial microbes than compared to yogurt or store-bought Kefir drinks.

To make kefir home, obtaining some quality milk and grains is needed—these unique grains must be first hydrated before they may be used.

A simple recipe begins by adding these starter grains to the milk and allowing it to ferment for about 24 hours at room temperature, giving you your very own delicious homemade milk kefir.

4 – Yogurt

Yogurt is a dairy product that can be enjoyed in many different ways.

It has a thick, creamy texture and tangy, sour taste that comes from the fermentation of milk by cultures of friendly lactic acid bacteria.

Unsweetened yogurt can be used as a great substitute for sour milk in baking recipes like cakes and muffins, as well as in more savory dishes such as soups and sauces.

In addition to being an excellent cooking ingredient, yogurt provides essential vitamins and minerals that are essential for our body’s functioning.

Plain Greek yogurt makes an easy snack or breakfast that is packed with protein, calcium, potassium, and probiotics to improve gut health.

5 – Cream Cheese

Cream cheese has been a creamy, delicious staple for centuries.

Originally produced in Europe during the 12th century, cream cheese is now widely enjoyed all across the globe.

Cream cheese is unique for its ultra-creamy texture and mild taste that’s distinct from other types of cheese.

It’s able to hold up to other flavors beautifully, making it a great addition to savory dishes or sweet desserts.

For those looking for a substitute for sour milk due to dietary restrictions, cream cheese is actually an ideal swap.

Simply mix one tablespoon of lemon juice or vinegar with each cup of cream cheese to mimic sour milk’s signature tang.

This swap will work perfectly in any recipe calling for sour milk.
