2. Let it sit out on your counter until it reaches about 65 degrees. I pulled mine out of the fridge and put it on the counter for about 7 hours.
3. Shake the jar profusely. The butter will separate from the buttermilk. If you have a really good shaker, (my husband, in this case) it may only take 5 minutes until you have a big mass of butter in the jar. It may take up to 20 minutes. Just keep shaking until you have a clump of soft butter.
4. Drain off the buttermilk and rinse. I put mine through a strainer, then put the buttermilk in the fridge to use for pancakes. I then rinsed a little water over the butter to get the remaining butterrmilk off.
4. Add a little salt. Then put it in a little container and refrigerate. It will harden when cool, just like regular butter.
That's it! It's really that easy. Enjoy!
