But she had changed her opinion since being on the show.
"Since I've been back I've been a bit more adventurous with my diet. Now I eat heaps of it, I cook heaps of curries."
But that enthusiasm hadn't extended to attempting to serve up Thai food in her cafe.
While Harper admitted her dishes were bad enough to see her sent home, she defended her "massacred" rice.
"It makes it hard with the rice because (the judges) don't eat the meal for two hours. It was just sitting there cooking, it would have been overcooked."
Her advice for fellow MasterChef wannabes was to practice, practice, practice.
"Be more adventurous with your food and be careful with your presentation," she said.
