Butter has to be one of the simplest things to make. Sure you can buy a tub or box of butter in the grocery store but making homemade butter with your kids is so fun. It makes a wonderful gift too. It's easy to mix in honey or jam for an extra special treat.
Whip as much heavy whipping cream as you want. You will watch it turn to whipped cream, then curdle, and them magically the butter solids separate from the buttermilk. The butter fat will cling to the mixer, leaving the buttermilk in the bowl. (You can use a stand mixer, hand mixer or even a mason jar with two marbles and shake.)
Remove all of the butter and rinse under cool water to remove any buttermilk. The butter will last longer since the buttermilk spoils fast than the butter fat. Fold the butter over itself to squish out all liquid. Now it's ready to eat! It will be firm like real stick butter. You can now add salt, honey or jam to it and whip it up.
Store your butter and buttermilk in the fridge. You can drink the buttermilk or use it in cooking.
