We had beached the boat and stepped out on the recently cleared spit of land. The ground had a light dusting of white sand over
an under layer of dried black mud. It looked like a recently frosted chocolate cake, though the frosting was spread a bit thin for my taste. The ground was solid, but we knew from experience that it was full of fiddler crab holes, and would be underwater at the first super-high tide. Mysteriously, to us anyway, someone wanted to build a house there. Read this line from the text:
It looked like a recently frosted chocolate cake, though the frosting was spread a bit thin for my taste.
What does this line suggest about the narrator?
The narrator likes lots of frosting.
The narrator thinks about different kinds of soil.
This is most likely what the statement is meant to indicate. The author uses the idea of frosting and cake as a metaphor to talk about sand and mud. It is not meant to be read literally, as the topic of food is irrelevant in the text. What the author means is that the layer of sand (what would be the "frosting" in the chocolate cake) was too thin. The overall meaning is that the soil is not particularly desirable because there is not enough sand, and the author prefers sand to mud.
