Looking for a weekend project? This is a great activity for kids and adults alike! For this holiday weekend, make some special butter to elevate your Easter brunch game.

In the Southern Appalachian Mountains, most families owned only a few cows. Because of the terrain, cows were more difficult to care for, so instead of raising cows for beef (which would mean raising a lot of cows!), people kept cows for dairy. This meant that they had to milk their cows daily in order to keep getting raw milk which they could turn into important foods like cheese and butter.

While you can make butter straight from milk (known as sweet cream butter), the best tasting butter is cultured first. Think creamy with a hint of tanginess, with all the melty golden goodenss of sweet cream butter.

What does “cultured” mean?

We aren’t talking about visits to the opera or art museums. In the world of dairy, cultured refers to milk that is fermented with lactic acid bacteria (the good type of bacteria!). Basically, we add something that already has an active culture—in this experiment we’re using sour cream—and mix it with milk to encourage growth of these yummy, healthy bacteria. It’s a similar process used to create other dairy products we love, like yogurt and cheese. This used to happen naturally, as cream just sat around for a day or two before refrigeration.

So how do we get butter from this “cultured” dairy?

Great question. We beat it!

Have you ever had whipped cream? That’s cream well on its way to becoming butter. And it is exactly what the name says—it’s whipped until there’s enough air in the cream to make it almost solid. If we kept beating that whipped cream, it would eventually become butter.

In scientific terms, what beating cream—or churning, as it is known—does is break the oil-in-water emulsion. Think of little molecules of fat totally encased in water—this is the cream. As we churn the butter, those protective bubbles of water get broken and pushes the fat molecules together to make bigger and bigger clumps until we have a nice solid piece of butter that is a conglomeration of all the fat (or most of the fat) in the cream.

Think of it like making a snowman—the snowflakes start to stick together until eventually you have a giant ball of snow! The fat molecules in the cream behave similarly.

After we finishing churning, we want to try and get any remaining liquid out of our butter, so we knead it. Kneading is fancy food word for basically pushing and mixing something solid. Here we are pushing and squeezing as much as we can. Then, we rinse our butter, maybe mix in a bit of salt, and then we eat it!

What you’ll need:

  • 2 cups heavy cream
  • ¼ cup sour cream (full-fat), whole milk plain yogurt, or buttermilk
  • ¼ tsp salt

 

Step One, Day One:

Measure out 2 cups of cream and mix in ¼ cup of cultured dairy (sour cream, yogurt, buttermilk) until combined.

Whisk the cream with the sour cream or other cultured dairy.

Place in a jar or bowl and cover with a towel. Let sit at room temperature for 18-36 hours. It should start to smell tangy and sour.

Pour cream mixture into jar.

Cover and let rest overnight.

Step Two, Day Two:

After your cream has sat for at room temperature, cover the jar with plastic wrap and refrigerate for 1 hour. Time to churn! There are a few different ways you can do this. If you have an old-style churn, you can beat it with a dasher. If you have a stand mixer, you can beat it with the paddle attachment. If you don’t have either of these tools, you can simply use a mason jar or Ziploc bags. If using bags, we highly recommend double bagging it!

Pour the cultured cream into whichever method you are using. Begin to beat or shake the butter. If using a mason jar or Ziploc bags, proceed to shake vigorously for 15-30 minutes. You may want to have a partner to take turns with!

Churn for 5-15 minutes depending on method used.

Step Three:

Place a mesh strainer lined with cheesecloth over a bowl. Pour churned contents into strainer and slowly start to push butter into a ball, squeezing out any additional liquid as you do so. The liquid you are straining out is buttermilk, which you can save to make more butter or some really delicious biscuits!

Once butter “breaks”–it will form a curd-like mixture and there will be visible liquid separated from the fat–strain off buttermilk into bowl using strainer lined with cheesecloth.

Wrap butter in cheesecloth and squeeze out remaining liquid.

 

Step Four:

Place the lump of butter in a clean bowl and pour about ½ cup of ice water over it. With a spatula or the back of the spoon, press the butter down into the water with the back of a spoon or spatula. Pour of the water and repeat process until water is clear.

Rinse butter with water and press into ball, squeezing out extra liquid.

Step Five:

Drain off the water completely. If you’d like, you can add the salt at this time. Sprinkle it over the lump and knead it in with your hands.

Shape into ball or log and pat dry.

Your butter is finished! Store in the refrigerator to keep it fresh. Your butter should be good refrigerated for 2-3 weeks.

Enjoy on your favorite baked good or use in cooking!
