One thing that always bugged me is that bbq sauce tends to come with a screw top, unlike ketchup or mustard, which comes with pour caps.
So when mom finished off a kraft salad dressing, I throughly washed the pour cap off, and tossed it on top of the fridge.
I'm not sure how long ago I did that, but tonight, the BBQ sauce once again betrayed me!
... and made a mess, so I remembered the saved cap.
I angrily threw the original cap in the garbage (It knows what it did) and screwed the pour cap on in it's place.
Since it's the same brand, and I'm guessing the same bottle, it mounted just fine.
And now the BBQ sauce is under control! (now it does what I tell it.)
I like this solution because I don't have to rinse out a plastic bottle, and washing the cap of a salad dressing bottle is super easy.
