Here’s the dirty little secret: a standard stick of butter is 1/2 cup. Yes, half a cup. That’s it.
So, when a recipe calls for 2/3 cup, you can’t just grab one stick. You need more than one, but less than two.
You’re now in Butter Purgatory. Welcome. It’s greasy here.
The Math That Drives Bakers Insane
Let’s crunch the numbers. One stick = 8 tablespoons. 2/3 cup = 10 tablespoons plus 2 teaspoons.
So, you take one full stick (8 tbsps). Then you need 2 more tablespoons from the second stick. Plus two little teaspoons.
You are now that person squinting at a butter wrapper at 9 p.m. on a Tuesday. Own it.
