Restaurateur, food writer and novelist Prue will be joining Paul Hollywood as judge of The Great British Bake Off when it returns to screens later this year.
And the two judges will be joined by new hosts Sandi Toksvig OBE and Noel Fielding.
Speaking to The Sun newspaper, Prue said that the show would prove to be very different in its new home and that's a good thing.
“I think what would have been fatal is if they had tried to simply do exactly the same thing and replace Mary with someone very like Mary and to replace Sue and Mel with similar cookie-girl comedians," she said.
Prue suggested: “I think it would have been really hard to get it right. But if we’re all very different, it will be different.
“The main thing that will not change is the contestants because they want to make sure they’re good bakers. I love the fact that they’re mainly concerned in finding the best baker and also not humiliating anyone."
Chatting to the tabloid, Prue went on to reveal she had called Mary Berry before accepting the job.
"We’ve known each other a long time but I wouldn’t say we’re alike. I hope I last as long on Bake Off – that would be a terrific triumph," Prue added.
The Great British Bake Off will air on Channel 4 later this year.
