What is the most important rule to consider when using fondant why?

The most important rule to consider when using fondant is: Keep it cool and dry.

Here's why:

* Fondant is temperature sensitive: It softens and becomes sticky at room temperature, making it difficult to work with. It can also melt and lose its structure, especially in warm environments.

* Moisture is fondant's enemy: Excess moisture will cause fondant to become sticky, sag, and crack. This can happen from humidity, condensation, or even the warmth of your hands.

How to keep fondant cool and dry:

* Store it in an airtight container in the refrigerator: This will prevent it from drying out or absorbing moisture.

* Work with small portions at a time: This will keep the rest of the fondant cool and dry while you work.

* Use a fondant smoother or rolling pin dusted with powdered sugar: This will help to prevent the fondant from sticking to your tools.

* Avoid using your bare hands: Use gloves to work with fondant, especially if your hands are warm or sweaty.

By following this rule, you can ensure that your fondant stays smooth, pliable, and easy to work with. This will lead to better results and a more enjoyable cake decorating experience!
