Basically tells you have to make various dishes saying without specific amounts and just going more on feel and what tastes good.
I love this tip about adding anchovies to pasta sauce to get a very rich flavor on the cheap.
Honestly like to think of it as the "stoned but competent" cookbook because the directions are quite easy to follow and come out tasty :)
Also the material they used for the "flexible" edition is really nice to use as you cook.

This is how my mom taught me to cook, and she decided (unilaterally I assume) that it was the definition of gourmet cooking. I went a lot of years thinking that was the literal definition, ha. Though in retrospect, it is not 100% wrong, and I don't think she was joking when she said it.
