How to Make Your Own Butter

Think of this as a science project that illustrates how a liquid can transform into a fatty solid. A delicious science project that requires a lot of elbow grease.


  • Step 1: Pour cream Pour the cream into the glass jar.
  • Step 2: Add marble Add the marble and close the jar tightly.
  • Step 3: Shake Shake. And shake. And shake some more. Now… continue shaking.
  • Step 4: Keep shaking After several minutes, the cream will start giving off its liquid and getting chunky; this indicates the butter is starting to form. Keep shaking!
  • Step 5: Pour into strainer When you can see lumps of butter in a milky liquid, pour the contents of the jar into a strainer set over a bowl.
  • TIP: The liquid that drains through is actual buttermilk. Use it for pancakes or ranch dressing.
  • Step 6: Extract liquid With clean hands or a spoon, press on the butter in the strainer, extracting whatever liquid remains. Let it drain.
  • TIP: If you prefer salted butter, add a teaspoon of salt and blend it in.
  • Step 7: Chill butter Remove the butter from the strainer. Roll it into a log and wrap it with parchment paper or press it into a pottery bowl, and chill it in the refrigerator.
  • Step 8: Spread butter For an immediate treat, immediately spread the fresh butter on the most delicious bread you can find. Your hard work paid off!
  • FACT: You’d need 21 pounds of fresh cow’s milk to make just one pound of butter.
