Speaking with WSJ. Magazine about her upcoming Pepper Thai Cookbook, the famous grandmother -- who first gained celebrity status as Chrissy's funny and outspoken mom -- reflected on her choice to dedicate the book to Jack.
"We talk about him every day," Pepper shared. "Luna talks about him every day, and that's how we grieve."
"Today was your due date. we love you forever," Chrissy wrote, adding a purple heart emoji. The accompanying photo showed her wrist with a beaded bracelet with Jack's name spelled out, as well as two bracelets above it with Luna and Miles' names on them.
Pepper, however, also opened up about the inspiration for her new cookbook, which she said came from her daughter -- who has published several cookbooks of her own.
Pepper said that Chrissy "put a lot of trust in me and told me that I was the best cook and that I need to write these recipes down."
"And I'm so glad she did," she added. "Now I have a book and something that I can pass down to her, Luna and Miles."
The Pepper Thai Cookbook: Family Recipes from Everyone's Favorite Thai Mom comes out April 13.
