First, grab your trusty one-cup measuring cup. Fill it up to the one-cup line—that’s your starting point. Now, mentally divide that cup into three equal horizontal sections. ⅔ means you take two of those three sections.
In practice? That’s a little more than half a cup. Actually, it’s exactly half a cup plus two tablespoons. Bingo! You can just fill your cup to the ½ cup line, then add two more tablespoons. Simple, right?
But wait—what if you don’t have a measuring cup at all? Don’t panic. A standard mug holds about one cup, so fill it two-thirds of the way up. Your eye is surprisingly good at judging thirds once you know the trick.
