Let’s be honest: precision is great, but your sanity is better. If you don’t want to do the two-measure dance, just eyeball it.
For half of 1 1/4 cups, think of it as a little more than half a cup. Fill a 1/2 cup measure, then add a generous splash—about two tablespoons worth.
Actually, let me give you the exact tablespoon version: 5/8 cup equals 10 tablespoons. So just scoop out 10 tablespoons and call it a day. No measuring cups required.
(Pro tip: if you’re out of tablespoons, that’s 5 fluid ounces. Or just use a shot glass. I won’t tell anyone.)
