How To Make Buttermilk

Buttermilk is something usually thought of as belonging to North American food culture, but is actually probably one of the oldest fermented drinks there is.

Buttermilk is typically just the liquid that has been left behind after churning butter, but modern buttermilk is a uniquely funky, acidic dairy drink that can add a ton of flavor to all kinds of recipes.

While a lot of stores will keep buttermilk in stock, there are just some places where you can’t get it, no matter how hard you try and look.

For those that find themselves bereft of buttermilk, here’s how to easily and simply make your very own?

Just What Is Buttermilk?

Buttermilk is really two different things masquerading as one product.

In the traditional sense, buttermilk is the liquid that has been left over after churning butter from cultured cream.

After removing the coagulated butterfats from the cream, which would then be removed, washed, and salted to turn it into butter, the leftover liquid would have been left, probably for a long longer than was really safe.

In an ensuring natural process, lactic acid-producing bacteria would then begin to ferment this leftover cream, thickening and flavoring it and turning it into buttermilk.

Modern buttermilk, however, is a bit different, as it is usually produced in a safe and controlled environment. Lactic acid-producing bacteria are typically added to milk and it is encouraged to grow and ferment the milk, and then pasteurize it once the desired level of acidity has been reached.

While the buttermilks that you can find in supermarkets are perfectly delicious, there is nothing quite like a buttermilk made from scratch.

The Process Of Making Simple Buttermilk

Making a simple buttermilk at home is actually a surprisingly easy process, and is technically more along the lines of a cheater buttermilk than a traditionally cultured, churned cream.

It really is as simple as adding 1 tablespoon of vinegar or lemon juice to a cup of milk, stirring it, and letting it sit for around 10 minutes.

The highly acidic vinegar or lemon juice reacts with the milk solids and curdles it, changing up the texture and enhancing the flavor, while the acid changes the flavor of the milk itself to something much tastier.

If you find yourself without any kind of buttermilk to use for a recipe that needs it, this will work perfectly fine.

Does It Matter What Milk You Use?

If you were making completely homemade buttermilk, you would need to use only the finest real milk, with as little pasteurization or homogenization as you could manage, to ensure that it would culture properly.

For this simple method here, though, you really can use any kind of milk you want.

Since all that’s happening is the milk solids are slightly curdling and the whole thing is becoming more acidic, you don’t need any kind of special milk to still end up with buttermilk.

The only thing you might want to keep in mind is that buttermilk tends to be quite rich and fatty, so you will probably want to use whole milk, rather than regular milk, for this recipe, as otherwise, it might not taste just right.

Could You Make Buttermilk Entirely From Scratch?

While the above method will make a buttermilk that is perfectly usable in recipes, you could absolutely do it all from scratch if you wanted to.

This is really the kind of thing you would do if you happened to keep a cow around the farm, but if you also happened to have some unpasteurized, totally un-adulterated milk lying around, you could still do this.

To start, you want to leave the milk to culture for a little bit.

While you could absolutely just hope for the right kind of bacteria to find your milk, your best bet would be to introduce your own bacteria to get the process started.

Ironically, the best way to do this safely and securely is to use a little bit of already-prepared buttermilk, or even yogurt. So long as the packet says that it is made with an actual live, active culture, then you can just put a little bit of it inside of your milk and let it go.

After letting the culture develop for a while, up to around 24 hours in fact, you should then churn out the butter, either by shaking it really hard for absolutely ages or putting it into a butter churner.

After separating the butter, you would be left with some homemade buttermilk, ready to enjoy.

Of course, this makes the whole thing take absolutely ages, so you might be better off just using a bit of vinegar and some regular milk.

    This is soured milk used as a buttermilk substitute. It is not buttermilk.2 stars

  2. Donna says

    I was always taught to take out 1 tbsp of milk before adding in the lemon or vinegar so you still end up with one cup of buttermilk (if that’s what your recipe calls for). Probably not a big deal if you are using the buttermilk for fried chicken but if you are using it in baking, I would think it’s best to use the precise amount required by the recipe.

    This IS NOT how buttermilk is made…this is a buttermilk substitute!1 star
