Good evening, I am trying to collect the maximum of food-related English idioms. Such as ...?

* Don't over-egg the pudding.
* He gave them a dressing down.
* You don't have to bring home the bacon.
* He kept as cool as a cucumber.
* She looked like butter wouldn't melt in her mouth, but she was a tough cookie..
Would you tell me more ?
Update: Thank you Fan Girl and Dunny. I understand the meaning.
To the next people, please, give me the meaning, I am not native speaker !
