I think this is not just because of this dish. Their contradiction should have accumulated for a long time. This is just a flashpoint. And the male host should really control his emotions, private affairs can be solved outside working hours, and slamming out the door is really a bit too much.
The hostess may have been patient for a long time, but she shouldn't say it in the workplace. She can communicate privately.
As public figures, they should not bring negative emotions to the public.
I hope they can communicate well and make peace.
