Content: That's a lot of shaking, though it does the trick when you need just a little buttermilk. If you need a larger batch, pour the heavy cream into a mixer and beat it at high speed. It will also turn into whipping cream first but if you keep whipping, it will separate out into butter and buttermilk. Don't Waste the Butter
The really neat part about this trick is that you're actually making two ingredients at the same time. There's no need to let that butter go to waste, you just need to process it a bit to make it useable. Knead the separated butter under cold water for a couple minutes to remove any remaining buttermilk. It will spoil very quickly if you skip this step. Then salt your butter if you like and store it in the refrigerator until you're ready to use it. Homemade butter has a relatively short shelf life, so enjoy it within a few days.

Store-bought buttermilk isn't real buttermilk at all.
