What is table salt (fine)?
Fine table salt consists of small, closely packed crystals. In baking it balances sweetness, sharpens other flavors, and influences yeast fermentation and dough structure, so the salt type and amount both matter.
Keep it dry and covered. This record applies only to fine table salt, spooned without compression and leveled; it scales to about 288 grams per US cup, but a scale or teaspoon measure is safer for the small quantities used in recipes.
