Common Mistakes to Avoid When Using RKT in Cake Decorating

When using RKT in cake decorating, there are some common mistakes that can easily be avoided with the right knowledge and technique. One of the most common mistakes is not allowing the RKT mixture to cool and set properly before shaping it.

It is important to give the mixture enough time to firm up so that it holds its shape and can be easily molded into the desired form for cake decoration. Rushing this step can result in a messy and unstable base for your cake decorations.

Another mistake to avoid is not properly sealing the RKT shapes with a layer of melted chocolate or royal icing before applying fondant or other decorative elements. This can result in the fondant not adhering properly to the RKT, causing it to slip or sag. Taking the extra step to seal the RKT will ensure that your decorations stay put and look professional.

Additionally, using too much pressure when shaping or sculpting RKT can lead to a dense and heavy structure that may not hold up well on the cake. It’s important to handle the RKT delicately and use gentle pressure when forming shapes or figures. This will help maintain a light and airy texture while still providing stability for your cake decorations.

By being aware of these common mistakes and taking the necessary precautions, you can ensure that your RKT cake decorations turn out beautifully and add an impressive touch to your baked creations.
