How to Make Butter
You'll be surprised by how easy it is.
To sum up:

Content: Note: Unless you made cultured butter, this buttermilk will not perform like the buttermilk you buy from the store. You need to add vinegar or lemon juice if you want it to react properly with baking soda. Now you’re left with (mostly) just the butterfat. Technically, you could eat the butter as-is, but if you do one more step, it will last longer. That extra step is this: You need to wash any remaining buttermilk out of your butter so it doesn’t sour. Scrape your butter into a bowl of VERY cold water. You can even use ice water if you wish. Squeeze and knead your butter to release the buttermilk.
