Nadiya: I didn't know you had to turn the oven on
She's baked for Mary Berry and the Queen - but when she was younger, Nadiya Hussain didn't even know how to use an oven.
She told Newsround that her mum used the oven to store pots and pans.
It wasn't until she went to school that she learned how to bake.
Nadiya popped by to answer your questions and chat about the new series of Junior Bake Off.
