The royal has been cooking meals for frontline NHS staff during the global health pandemic.
She has been volunteering once a week alongside professional chefs organised by the millionaire British financier Ian Wace.
According to MailOnline, the group have been making up to 59,000 free meals a week as they working 24-hours a day.
The meals go to frontline staff in hospitals across Greater London including Barts, King’s, Epsom and St Helier.
Apparently Sophie has been coming to volunteer on the sly once a week and has been preparing and cooking food as well as cleaning up.
This week, she was packing up pre-prepared vegetables as well as making wraps and lemon and raspberry tarts, wearing a face mask, gloves, whites and an apron.
Much of the work has been undertaken in the kitchens at the Chelsea headquarters of asset management firm Marshall Wace in London.
The volunteers make two meals every day, lunch and dinner under the watch of head chef Mark Brown, a former chef to Sir Elton John.
It comes after Meghan and Harry were revealed to be volunteering in Los Angeles.
The former royals volunteered with charity Project Angel Food on Easter Sunday and returned to drop-off non-perishable meals to 20 more vulnerable people in the city.
They have also been delivering food to those who were critically sick during the quarantine.
Project Angel Food serves 1600 meals a day, which will now rise to 2000 during the coronavirus crisis, ensuring some of those most at risk are fed.
