WA mother-and-son duo Lisa and John Krasenstein have earned themselves a place in the My Kitchen Rules hall of fame.

For their first instant restaurant, the pair received a perfect score from the judges for every dish they plated up — something that has never before happened on the show.

Pete Evans called them the “strongest team in MKR history” based on their initial offering, which was deceptively simple on paper: seafood cocktail, lamb shanks with mash, and raspberry cheesecake.

The cheesecake, John’s piece de resistance, was actually a deconstructed dessert around a flummery (whipped jelly) dome, taking the table by surprise.

“John said not to overcomplicate what we write on the menus, because if something goes wrong we can leave an element off,” Lisa told AAA.

“That was tactic; to make the menu look simple. Like the raspberry cheesecake, you wouldn’t have expected what we put out.”

But ultimately, John said they just wanted to show that good old-fashioned home cooking could be exceptional.

“We wanted to bring to the competition food that we eat at home,” he said. “You can bring a fine-dining twist to it, but it is home cooking at the end of the day. We didn’t want to reinvent ourselves.”

The team confessed they were hoping to get sevens for their first cook so to get 10s for every dish was unexpected.

“I felt like I was in a dream,” Lisa said.

“By that point I was delusional with exhaustion and excitement.”

John added with a laugh: “I remember Pete saying ‘You got a perfect score’, and Mum turned to me and said ‘Is that good?’”

Lisa said she was “absolutely racked” with stage fright.

“We are just normal people, we aren’t used to this,” she said.

“We tried our hardest and did our very best, and I wanted to support John and be a good partner to him. To get that result was a real surprise and an honour.”
