Saya Cultured Butter boasts a taste and aroma that is truly something special. Cream is fermented and soured using a lactobacillus culture to create crème fraîche, and then it's churned into delectable butter. Upon opening the package, you'll enjoy a tangy, creamy flavor that just keeps getting better. As the culture develops, the butter takes on a delightful, cheesy flavor and rich, pungent aroma - a hallmark of cultured butter.
