How to Measure Butter Accurately
US sticks are pre-ruled: cut on the tablespoon lines and you need no cup at all — 1 stick is 8 tablespoons, 113 g, half a cup. For a measuring cup, press cold-cut cubes in and level; softened butter packs into a cup with voids, so for softened butter the water-displacement method (or the stick lines) beats the cup.
Storing Butter & Common Substitutes
Storage
Refrigerated in its wrapper, 1–3 months past purchase; wrapped airtight and frozen, up to a year. Butter absorbs refrigerator odors within days, so an extra layer of foil pays for itself. Salted butter keeps about twice as long as unsalted.
Substitutions
Margararine swaps 1:1 by weight. For baking with oil, replace each cup of melted butter with 3/4 cup of neutral oil plus a tablespoon of milk or yogurt. Coconut oil works 1:1 melted where its flavor fits. Applesauce halves the fat: replace up to half the butter in quick breads.
