You can substitute the Jell-O shot cups for 2 oz. condiment cups with lids. These actually work great if you plan on making your banana split jell-o shots in advance. This will allow you to cover each with a lid and easily stack them in your refrigerator until you are ready to garnish and serve them. You can find these in your grocery store where you find all the disposable storage containers like bags, plates, and plastic wrap.
