Cultured butter is made from fermented cream and has live cultures in it. It has a stronger taste than regular butter, one that I find very tasty. It is somehow more “buttery” tasting. This is actually how butter used to be made – cream was collected for several days before it was churned into butter. Michael Ruhlman talks about how to make your own, which I am going to try. If you haven’t tried cultured butter, I urge you to try it. It just tastes so much better!
