Let’s say you’re making a double batch of chocolate chip cookies (a noble goal). The recipe calls for 2/3 cup of sugar once, but you’re doubling it. That’s two 2/3 cups of sugar. You could measure 1 1/3 cups, but weighing it is even easier: one cup of granulated sugar weighs about 200 grams, so 1 1/3 cups is roughly 267 grams. No cups, no drama.
But if you don’t own a scale—and I respect your minimalist kitchen—just use the 1/3 cup measure three times. Wait, that’s too many? Let’s do the math: two 2/3 cups = 4/3 cups = 1 1/3 cups = four 1/3 cups? Nope, that’s wrong. It’s four 1/3 cups if you have two 2/3 cups? Let’s break it down again: one 2/3 cup = two 1/3 cups. So two 2/3 cups = four 1/3 cups. Yes! That’s right!
