And during Wednesday's episode, the feisty brunette's sudden silence quickly angered judges Pete Evans and Manu Feildel.
During an extremely awkward moment, the data scientist, 32, couldn't quite make up her mind as to whether she loved or loathed Victor and G's curry dish at their Instant Restaurant, Chi.
'I was so confused, but it was a tasty dish of confusion,' declared Bianca.
Seemingly wanting a clearer review, Pete asked: 'So you liked eating it?'
Bianca, struggling to articulate her thoughts, responded: 'I don't know how to answer that.'
As she continued to fail to the right words to summarise her thoughts, both the rest of the group and the judges became frustrated.
'How hard is it?' demanded Pete.
Did you enjoy it? Sure what? Sure yes or sure no?' continued Manu.
Even retired beauty queen Veronica piped in, adding: 'Come on, it's not hard. You're being immature here, just answer the damn question, seriously.'
Trying to justify her lack of solid opinion, Bianca said in a piece to camera afterwards: 'My tongue kind of just shuts down and says, “What are you doing to me?” There are a thousand flavours in here... I'm confused.'
The drama continues to be dished up!
