You can steam your cake….but you do need a hand held steamer, or you can apply a glaze. Glaze is 2 parts alcohol to 1 part corn syrup. Brush on, it will be a bit tacky, don’t touch, let it dry. You could increase the alcohol, it will dry faster. You could also use piping gel thinned with either pure lemon extract or alcohol. I would roll out a piece of fondant, let it dry, and experiment and see which technique you like best, if any.
Hope this helps. 💜
