My mom is a really good cook. We used to make dumplings together.

I'm actually a good cook.

I'm a good cook; one of my specialities is reindeer and potato pie.

I'm actually a really good cook, and people don't believe this about me!

A good cook is like a sorceress who dispenses happiness.

The cook was a good cook, as cooks go; and as good cooks go, she went.
