Do you need to put anything in a Jello mold before the gelatin?

You don't need to put anything in a Jello mold *before* the gelatin. The gelatin solution is what sets and forms the shape of the Jello.

However, you can do a few things with the gelatin to make your Jello more interesting:

* Add fruits, vegetables, or candies: This can be done directly into the gelatin mixture before it sets.

* Layer different flavors: You can make multiple colors or flavors by pouring different gelatin solutions into the mold one at a time, allowing each layer to set before adding the next.

* Use decorative molds: There are many different types of molds available, including hearts, stars, and flowers.

* Create a "Jello shot" base: You can add alcohol to the gelatin mixture for a fun, boozy dessert.

Remember to follow the instructions on your gelatin package for best results.
