Every once in a while we come across a culinary tip that’s so spectacularly simple, we literally feel ashamed of ourselves for not being aware of it before. We know, we know, we surely sound just a TAD dramatic right now, but once you get the down-low on this trick for yourselves, you’ll be second-guessing your storage knowledge, too!

So, here’s the deal. You know those disposable Glad storage containers that everyone and their mother has lining the shelves of their cupboards? Of course you do! These kitchen mainstays are used by master home chefs and microwave dinner fanatics alike because they are durable, easy-to-clean, and best of all, cheap.

And though their design may look simple, these food-saving contraptions are actually much, MUCH more complex than you may think. You see, the genius of this product rests entirely in its lid…

Yep, THAT one.

Now, it’s fair to say that you’ve never sat around and wondered why the makers of this product chose to add a circle to the tops. We always just assumed that it was either part of the aesthetic, or even perhaps a good spot to press when securing the lid.

Fair assumptions, right? Well, what if we told you that the circular feature was actually made for THIS:

If you’re not too sure what you are looking at here, don’t worry. Our minds were so totally blown when we first laid eyes on it that we couldn’t quite grasp the brilliance either.

It turns out that Glad isn’t into haphazardly adding geometric shapes to their containers for no reason. The superb designers included the circle so that it could act as a spill-proof, snap-on lid for their tiny dressing cups. Get it now?!

We’re absolutely going gaga over this idea and—like the rest of you out there—we are wondering why we never heard of it sooner!

The salad dressing storage secret that was right under our noses

Believe it or not, Glad actually has photographic evidence of these unbelievably nifty containers right on their website, so this tip isn’t necessarily akin to a hack or “secret menu”-worthy item.

Now, we’re not saying that we regularly browse the company’s website—after all, we always assumed that their iconic disposable food storage devices were foolproof. Just the same, it’s obviously time that we start reading the instructions since we’ve clearly been missing out on some good stuff.

Although Glad only plugs this obscure feature for its legions of on-the-go salad lovers, we have a host of ideas in regards to how we can all get the most out of this trick. Aside from dressing and greens, we can’t wait to try the snap-on cup with chips and salsa, pita and hummus, and even pie and whipped cream.

Hey, you learn something new every day!

We can’t wait to hear what you have to say about this little-known food storage trick. Have you been securing your salad dressing with the special Glad lids for a while? If so, how come you didn’t tell US about it?! What’s the best backpack-friendly dressing that doesn’t require refrigeration?
