In a perfect world each of us would have time to make home made salad dressing and measure out 1-2TB for each meal. Since reality is we do not have that time, I wanted to share this great product to portion control store bought dressing. This lid fits most store bottles, once screwed on the salad dressing bottle just squeeze and the top portion fills with exactly 2TB of dressing. No mess and there is no way to over fill (I mean we all have those days we "cheat" and give ourselves a little extra). Open the top and pour over your salad, veggies, or protein! Its that simple!
