The Tasteless Cuisine Facebook group was set up last November by Declan Cassidy from Mornington, Co Meath.
It has expanded rapidly during the current lockdown and now has almost 650 members.
Describing his reasons for establishing the group, Mr Cassidy said: I contracted Covid-19 in March of last year. But after recovering from the virus, I found that I had lost my taste and smell. Initially, I resorted to putting jalapenos into absolutely everything, including my morning porridge. However, I figured out that if this continued past three or four months, the chances of me getting my taste and smell back were diminished.
