Melissa then revealed that her parents handled the situation by explaining what the racist comments meant and why they were said, but told her not to pay any attention to it and to brush it off and be herself.
"It isn't until later in your life that perhaps you reflect upon the experiences that make you you and you realise what an impact it might've made," she added.
The MasterChef judge went on to say that whilst dealing with racism is "tough" and that she prides herself on her resilience and competence, she thinks "it's important to be vulnerable and to really pay attention to your emotions."
"If experiences in my childhood have helped me become strong then I can articulate those experiences and perhaps tell people out there that have gone through the same thing that they're not alone."
In a heartwarming message to children of varying ethnic background, Melissa remarked: "As a veteran outsider of many decades I would want to say to you that your place in this world matters. You do deserve to be seen and to be heard and for your heart and your soul to be accepted and you will find your people. So be kind to yourself in that process because this is the making of you."
Since she joined the new MasterChef judges Jock and Andy Allen, Melissa's popularity has soared to new heights, though she hasn't been immune from online trolling.
"I’ve spent a very long time learning how to be comfortable in my skin and that’s the best I can do," she explained in July.
"Not everybody is going to like what you do. Nobody is universally loved and I think when you can accept that you can focus on being the best version of yourself you can be. As for trolls and the like, I don’t want to let any of that noise weigh me down so I’m not paying attention to any of it at all."
With Junior MasterChef now airing on our screens, Melissa can't help but admire the sheer talent of the young chefs on the show this year.
"In a word, these kids were inspiring," she told Woman's Day in September.
"To have 14 enthusiastic, good-hearted clever and creative juniors to spend this season with was such a bright spot in a crazy year."
