If you have a standard set of dry measuring cups, grab your 1/3 cup measure. Two of those fill ‘er up to 2/3. Yes, it’s that simple—2 x 1/3 cup = 2/3 cup.
No 1/3 cup handy? No sweat. Use a 1/4 cup plus a 1/4 cup plus a 2 tablespoons. Wait, that’s math again—stick with me. Two 1/4 cups give you 1/2 cup. Then add 2 tablespoons (which is 1/8 cup) and—bam—you’re at 2/3. High-five the air.
What About Liquid Measurements?
Ah, liquids—the slippery villains of the kitchen. For wet stuff like milk or oil, use a liquid measuring cup with a spout. Pour until the meniscus (that little curved dip) hits the 2/3 line.
No 2/3 mark? Fill to the 1/2 cup line first. Then add 2 tablespoons plus 2 teaspoons. That’s exactly 2/3 cup. I know—teaspoons feel like cheating, but math doesn’t judge.
