[Eng.] cooking idioms

After doing a whole lot of exercises,  i found that my English is not that good at all.  Actually, my English is quite poor.  The fact strikes my confidence down.  Happen to see this quiz on BBC website and it's quite fun that you never know there's such an idiom.  See if you can get the correct answers.
