It’s no secret that butter makes everything taste better.
Adding unrivaled flavor, depth and structure to a range of dishes, butter is wonderfully versatile as both a sauce itself and the foundation for one. Butter emulsifies soups and stews while adding a boost of umami. It is a bread basket essential and the best spread for toast, bagels, scones and muffins.
When creamed for a cake or cookie batter, butter increases the loft and intensifies the sweetness. What would mashed potatoes, grilled steak or steamed asparagus be without that crowning pat of melting butter?
Transforming liquid cream into solid butter is culinary magic. Centuries ago, Irish women prayed to the goddess Brigid, patron of farms and fields, as they churned their fresh milk to assure it would become rich, smooth and as tasty as soft cheese. Throughout history, butter has been a food for celebration and served as a medicine, a healing salve for wounds and burns as well as treatment for bronchial ailments.
Whether shaken in a jar, turned in an old-fashioned butter churn or rotated in an industrial metal tank, the process works the same way. As the cream membranes break open, the fats separate and clump together into a ball. The liquid left behind, called buttermilk, is a thin and watery “skim milk,” not the cultured buttermilk on supermarket shelves. (I tasted that “skim milk” while visiting Minnesota’s Hope Creamery on a blistering hot August afternoon, and it was clear and cold and wonderfully refreshing.)
