It’d be nice if that bottle of vinegar would let you know exactly how much you’re pouring while you’re pouring it. Measuring Pours are bottle tops that only pour a certain specified amount when tipped over – special reservoirs with ball-bearing valves make it happen. They’re made with flanged seals to fit bottle necks from 3/4” to 1” in diameter. Choose from teaspoon, tablespoon, 1 ounce, 2 ounce and free-flowing (in case you’d like to eyeball it). Also available in a set of three (teaspoon, tablespoon, ounce) for $17.
