The good news is that, if you’re willing, you can make your own butter. Buy organic heavy cream. Mix it with the same probiotic culture used to make yogurt. Let it sit at room temperature for 24 hours to allow for fermentation. Refrigerate overnight. Whisk it until it turns into butter. With a cheesecloth, drain the buttermilk (or save it for other uses) and voila! You have made your own homemade butter. It is called cultured butter. Here again, the secret is moderation. 1 to 2 pats of real butter a day will do you good.
