She is seldom pictured cooking on Keeping Up With The Kardashians.

The mother-of-six said the motivation behind the cookbook - which will be published in October - were the constant requests from family and friends for recipes.

'I finally got so tired of sharing my recipes one-by-one with everybody that asked, that it just made sense to do a book and put it all together,' she told E!.

Kris may have kept her culinary skills under wraps until now, but she insists she is an avid cook, especially when it comes to her grandchildren.

'I make a really mean grilled cheese sandwich so Mason and Penelope love my grilled cheese sandwiches,' she said of daughter Kourtney's kids, according to the International Business Times.

For Kris, the 300-page cookbook represents what her family is all about.

'I think that what I love so much about our life is that we love to celebrate, we love tradition,' she said.

The 'momager' said spending time in the kitchen helps her to relax.

'[Cooking] is almost like the way that I calm down. Some people do things to relax, they’ll go play golf or have a sport. Me? I’m in the kitchen,” she said. 'Nothing makes me happier, so I hope I can share that with everybody else.'
