Cultured butter is dead easy to make. This butter is distinctly different from sweet cream butter, with a denser texture and slightly tangy flavor. “Cultured” means that the cream is fermented into cream fraiche/sour cream before being churned.
Perfect for your St. Patrick's Day soda bread, slathered thickly on any baked good, or melted over vegetables or fresh pasta, cultured butter is a richly flavored treat. This recipe is a 2-for-1 since you get fresh buttermilk too!
Letting the cream go sour adds a welcome, mild funkiness to this homemade butter. This recipe hearkens to European-style butters where flavor is something to be desired, not obliterated as it is under USDA guidelines.
