Gogglebox viewers were left disgusted during the latest episode.
The families on the Channel 4 show settled down to watch Remarkable Place to Eat, hosted by First Dates star Fred Sirieix.
This week, Fred was joined by Great British Bake Off winner Nadiya Hussain who took him to Yorkshire to visit popular tearoom, Betty's.
Nadiya told him he was "in for a treat" as she whisked him off to the venue which people often queue round the block to get in to.
While there, Nadiya said she couldn't not visit without sampling a Fat Rascal - a Yorkshire classic which is similar to a scone or rock cake.
While some of the Goggleboxers themselves didn't have a clue what one was, neither did Fred.
But eagle-eyed viewers watched as Fred committed a foodie crime - which they branded "pure filth".
One said: "Fred dunking his cake in his tea, pure filth right there #Gogglebox."
"RIGHT!!! Fred is now barred from Yorkshire!!!! We can’t have people doing stuff like that with scones!!! #gogglebox," a viewer raged.
A third added: "No, Fred, no! You can’t dunk a Fat Rascal, even though I’ve never heard of it before. #Gogglebox."
"This is appalling.... Dunking a scone. WTF. #Gogglebox," another said.
And the stars of the show also gasped in horror.
"You don't do that," exclaimed Lee Riley.
"Sacrilege," Sophie Sandiford added.
"He's going to get escorted of the premise in a minute," Sue added.
