Ingredients & Their Roles (The Formation)
· 8 oz (226g) Unsalted Butter, room temperature: The STAR. It provides flavor, tenderness, and that essential sandy texture. Unsalted butter allows you to control the salt level. Room temp is non-negotiable for proper creaming.
· 3/4 cup (150g) Granulated Sugar: Sweetens and, when creamed with butter, helps create a light structure.
· 1/4 tsp Salt: The flavor enhancer. It balances the sweetness and amplifies the butter’s richness.
· 1 1/2 tsp Pure Vanilla Extract: Adds a warm, aromatic depth. Avoid imitation for the best flavor.
· 1 Large Egg Yolk: Binds the dough, adds richness and color, and contributes to a tender crumb.
· 2 cups (250g) All-Purpose Flour: The structure. It gives the cookie its body without making it tough.
