Why does jello get rubbery on bottom?

* The bottom of the pan is too hot. When the bottom of the pan is too hot, the jello will cook too quickly and become rubbery. To avoid this, make sure to place the pan on a low heat setting or use a heat diffuser.

* The jello is not stirred properly. When the jello is not stirred properly, the gelatin will settle to the bottom of the pan and form a rubbery layer. To avoid this, make sure to stir the jello constantly while it is cooking.

* The jello is not chilled properly. When the jello is not chilled properly, it will not set properly and will become rubbery. To avoid this, make sure to chill the jello for at least 4 hours before serving.

Here are some tips for preventing jello from getting rubbery:

* Use a heat diffuser or place the pan on a low heat setting.

* Stir the jello constantly while it is cooking.

* Chill the jello for at least 4 hours before serving.

By following these tips, you can ensure that your jello will be perfectly set and delicious.
