For this recipe I used my Bullet. I poured in about a pint of cream and a small amount of salt into a "Bullet-Blender," turned it on... First it will make whipped cream but continue blending and shaking. It will take about 5 or so minutes. You will know you have butter when the liquid seperates from the mixture. Do a taste test to see if you have added enough salt.
When complete you can mold into sticks of butter or put it into candy molds and freeze for a later date.
*Don't add salt if you are going to use in chocolate making
*Add different ingredients for flavored butters such as garlic and parsley.
