I just learned a writing trick. Its one I'm certain I've been subjected to many times without ever noticing. And that's why it works.
Most books tell you over and over again what things look like. Very few ever describe a smell.
When you say something smells like steak cooking, everyone knows what you're talking about. They may not get the exact same thing as everyone else, but they get something.
I'll be using this. Probably sooner rather than later.
