Can you make jello using frozen pineapples?

You can't make traditional jello using frozen pineapples directly. Here's why:

* Enzymes: Frozen pineapples contain bromelain, an enzyme that breaks down proteins. Jello sets due to the gelatin, a protein. The bromelain would prevent the gelatin from setting properly, resulting in a runny, unappetizing mess.

* Water Content: Frozen pineapples release a lot of water when thawed. This excess water would dilute the jello mixture, making it too watery and again, prevent it from setting properly.

What you can do:

1. Use Canned Pineapple: Canned pineapple is already cooked and treated to deactivate the bromelain. It's ideal for using in jello.

2. Cook the Frozen Pineapple: You can cook the frozen pineapple to break down the bromelain and remove some of the excess water. However, this can impact the texture and flavor of the jello.

3. Make a Pineapple-Flavored Jello: You can use pineapple juice or extract to flavor the jello without using actual pineapple. This will give you a delicious pineapple-flavored jello that sets properly.

Remember, always check the packaging instructions for your specific jello mix to ensure the best results.
