MasterChef contestant Natalie, who has gained a reputation for her 'left field' ideas, elicited raised eyebrows from judges John Torode and Greg Wallace when she revealed the secret ingredient in her chocolate mousse.
'We've had chocolate mousse made with avocados ... potatoes, all sorts of bits and pieces, but this is the first time it's been made with sweet potato', said MasterChef presenter John Torode.
Fans were seriously unimpressed and took to Twitter to vent their disbelief. One viewer pointed out that 'Just because it's called SWEET potato doesn't mean you can use it for pudding.'

#MasterChefUK Who puts sweet potato in a chocolate mousse? That's one hipster idea too far ðŸ˜¬— Cate Tyrrell (@catetyrrell) April 19, 2017
While many others seemed to object to mixing vegetables and chocolate, calling it 'one hipster idea too far'. It turns out it wasn't all bad press though, as some fans were more optimistic, suggesting that it could count as one of your five a day.
Can we agree that you probably don't like the mousse because potato has no place in a chocolate dessert?? #masterchef— lauren brown (@aynsley_angel) April 19, 2017
The wannabe chef's pudding was made with chocolate, sweet potato, and coconut cream, and served with kirsch coulis and coconut and cinnamon crumb.
Last night's guests on the show, previous MasterChef champions Peter Bayless, James Nathan and Mat Follas, were less than impressed with the dessert. They said that it wasn't a mousse, and described its texture as 'grainy' and 'solid'.
Despite the negative feedback, Natalie's sea bass with ratatouille and a fennel and cucumber salad was strong enough to gain her a place in the quarter final, which airs on BBC One on Thursday.
Although swapping more conventional ingredients with vegetables seems to be somewhat of a fad at the moment, with dishes like avocado ice cream and courgette cake gaining popularity, it seems unlikely this particular cooking hack will catch on!
