From my personal experience in cake decorating, working with gelatine can sometimes be tricky, especially when it absorbs too much into the cake and affects texture. One method I've found helpful is to prepare a gelatine syrup and allow it to cool slightly before brushing it gently onto the cake layers. This helps seal the cake and creates a stable base for decorations. It's important to consider the type of cake you're working with, as spongy cakes tend to soak up liquids more readily. To counter this, chilling the cake before applying gelatine can reduce absorption. Additionally, using a light hand with the gelatine application ensures the cake doesn’t become soggy. Incorporating small floral decorations like baby's breath, as requested by some cake decorators, can add elegance but also require careful placement to avoid disrupting the cake’s surface. I recommend securing any decorative elements with a tiny dab of gelatine to keep them in place without affecting the cake’s moistness. Overall, patience and practice are key to mastering gelatine in cake decorating. Every cake varies, so testing this method on smaller batches or scraps can help you perfect your technique before working on a final piece. This approach has consistently worked well for me, maintaining both the integrity and aesthetics of decorated cakes.
