MasterChef Australia‘s latest couple are not holding back online after confirming their relationship post-filming.

Declan Cleary and Sarah Todd, who both appeared in the Back To Win series this year, have gone public with their romance and are now showing the love on Instagram.

On Monday, 27-year-old Declan left a suggestive comment on Sarah’s recent video, which showed her pairing mango, salt and chilli in ‘a weird food combination’ that she claims just ‘works’.

‘What’s your weirdest food combo that actually works? I’m testing out weird food pairings and had to kick it off with one I secretly love…’ Sarah, 38, captioned the post, which has garnered over 4,000 likes since being posted.

‘@HotToddyChilli Birdseye, mango and salt. Don’t judge, it’s already a fave in India! Swap it for green mango and it’s game over,’ she ended the post.

Fans of the foodie flooded the comments with praise for the unorthodox pairing, while also suggesting their own strange combinations.

However, Declan raised the temperature in the comments section with his own ‘saucy’ pairing.

‘Wow I bet some hot toddy would work well on papaya with lime and salt,’ he cheekily wrote.

The remark, though alluding to Sarah’s chilli brand Hot Toddy, also came across as flirty, considering her surname is Todd.

Sarah and Declan went public with their relationship on Sunday, revealing that they have already moved in together following the high-pressure show.

Speaking to Stellar Magazine, Declan admitted that despite their big age gap, the pair ‘instantly got along’, which saw them spend lots of time together behind the scenes.

However, it wasn’t until Sarah landed in an elimination challenge that Declan’s feelings became apparent, and he knew he needed to tell her how he felt.

‘As she’s walking into the elimination [challenge], I said, “Sarah, can I ask you something? Would you like to go on a date with me?” And she just looked at me and said, “You’re a bloody idiot”,’ he said.

While the poorly-timed invitation didn’t land the way he thought it would, Sarah eventually came around to the idea of them together.

‘After I got through the stress of the elimination and had a couple of days to recover, I realised it made sense,’ she said.

For their first date, the pair visited Grampians National Park for a romantic weekend away, exploring markets, eating at picturesque restaurants and going for walks in the central Victoria highlands.

Now, after wrapping filming on the show, Declan has made the move from Sydney’s Northern Beaches to Melbourne – along with his dog Sol – to be with Sarah and her 14-year-old son Phoenix.
