In real life, Moynahan, who just married investor Andrew Frankel and is the mom of son Jack, 8, practices what she braises.
"Everyone gets what I'm putting down on the table. He doesn't complain, though!" says Moynahan. "I cook all the time. We try to cook every night. When you're cooking, you know what's going in the food. You can control it. And it's fun."
Case in point: "I went to my son's school yesterday and he had written how to make chocolate chip cookies. He had the entire recipe down. He knew it from doing it. He had memorized it. He knows how to make cookies. It's a nice thing to do with your kids as well."
Researching the book was sweet, zesty and very hearty, says the actress.
"I got to go through all my cold recipes and call my brother and call my mother. Remember that thing we used to make together? Let's talk about it. It brought back a lot of memories," she says.
And congratulations are in order for Moynahan, who managed to pull off the impossible: a secret wedding, which took place in the Hamptons at a vineyard. In lieu of gifts, she asked guests to donate to Paul Newman's Hole in the Wall Gang.
"We'd rather have people give to that. It's an organization dear to our hearts," she says.
As fans of "Sex and the City" know, Moynahan played Big's wife on the show. Here's a look at her costar, Sarah Jessica Parker.
