Kate Winslet wants a pressure cooker for her 40th birthday.

The 'Divergent' star will reach the milestone age on October 5 and, although she wants a big bash to celebrate the occasion, she's hoping she'll be gifted the culinary device so she can start making some ''bone broths'' to keep her well throughout the winter.

She told E! News of her birthday plans: ''I'm going to look amazing and I'm going to celebrate in style. I'd quite like a pressure cooker. I want to start making bone broths!''

Her 'Steve Jobs' co-star Michael Fassbender chimed in during the joint interview with a puzzled facial expression, asking: ''What does that entail?''

Kate then explained: ''Taking a whole bunch of bones and putting them in a pressure cooker with lots of chopped up leeks and onions and celery and all that stuff and you make this amazing restorative bone broth ... You boil it up for like 12 hours and it cures you of all ailments.''

Clearly impressed, Michael, 38, offered to buy her the device, providing she makes him a broth in return.

He cheekily said: ''I will get you the pressure cooker if you will cook me one of those bone broths.''

Meanwhile, the stunning starlet - who has over 30 films under her belt - feels very content about going into the next chapter of her life following the success of the last few years.

And Kate - who has children Mia, 14, with first husband Jim Threapleton, son Joe, 11, with second spouse Sam Mendes and 21-month-old son Bear with current husband Ned Rocknroll - is determined to continue her success into 40s and already has a number of projects lined up for the future.
