How do you get dec a cake writing gel to dry?

It sounds like you're talking about cake decorating gel, not "dec a cake writing gel". There are a few different ways to make cake decorating gel dry faster:

1. Thinning the Gel:

* Add a little bit of vodka or lemon juice: This helps the gel to dry more quickly by evaporating the moisture faster.

* Use a piping tip with a smaller opening: This allows for thinner lines of gel, which will dry more quickly.

2. Adjusting the Environment:

* Use a hairdryer on a low setting: A hairdryer can help speed up the drying process, but be careful not to get it too close to the gel or you could melt it.

* Use a fan: A fan can also help to circulate air and speed up drying.

* Place the cake in a dry, well-ventilated area: Avoid areas with high humidity, as this will slow down the drying process.

3. Waiting Patiently:

* The gel will dry on its own: It may take a little longer, but the gel will eventually dry on its own.

* Be patient and don't try to speed up the process too much: If you try to dry the gel too quickly, it could crack or become brittle.

Important Note: Always test the drying time of your gel on a small piece of cake or parchment paper before decorating the entire cake.

If you're still having trouble getting your cake decorating gel to dry, you may want to experiment with different brands or try a different type of decorating product, such as royal icing.
