For years I would take a salad to someones house and would be fumbling for something to carry the dressing in. I tried plastic containers but they always seemed to leak. Then I tried glass jars, which worked better but it wasn’t as aesthetically pleasing as I would want. Then I saw the dressing bottles, some were plain and some had dressing recipes on it. I chose the one with recipes on it and some are really good! I would recommend every home cook get one.
