Baking Mistake Alert: Exactly How Many Cups Is 3/4 Stick of Butter?
American grocery store packaging relies on a specific standard. A standard US butter stick weighs 4 ounces (113.4 grams) and equals exactly 1/2 cup or 8 tablespoons. Four sticks comprise a standard one-pound carton.
When a recipe demands 3/4 of a stick, you calculate three-quarters of one-half cup. Mathematically, 3/4 multiplied by 1/2 yields 3/8 cup.
Hardly any commercial measuring cup sets include a 3/8 cup vessel. If you attempt to eyeball three-eighths of a cup inside a liquid measuring glass, surface tension and angled glass will distort the reading. The reliable manual method involves measuring tablespoons in 3/4 stick of butter: since one full stick holds 8 tablespoons, three-quarters of that stick contains exactly 6 tablespoons. To build that with standard measuring cups, pour 1/4 cup (which holds 4 tablespoons) and add 2 tablespoons.
