Any woman who’s fallen prey to the patronising art of mansplaining will know that it’s an experience akin to banging your head against a concrete wall.

It’s painful and pointless, yet that doesn’t stop certain men – and yes, in this case it is always men – feeling moved to patiently and very s-l-o-w-l-y explain things to us that a) we already know, or b) have no benefit or relevance to the situation at hand.

We’ve seen it happen on social media, we’ve seen it written into HBO’s Game of Thrones as a vital plot point and we’ve even seen a man try to explain the inspiration behind Indiana Jones’ iconic costume to the very same woman who actually designed the costume in the first place.

This week, though, we witnessed it on an episode of MasterChef UK. And it’s triggered an enormous response on social media.

During the show, Zaleha Kadir Olpin whipped up a nasi lemak — a fragrant rice dish cooked in coconut milk that is considered by many to be the Malaysian national dish — for the judges to try.

She served it alongside a spicy dish called chicken rending, which is, again, extremely popular in both Malaysia and Indonesia, as well as Singapore and Brunei.

“There was a special stall outside my school that sold the best nasi lemak so I used to save up pocket money on Fridays,” she explained, when asked why she’d chosen the recipe.

“The dish is very special to me.”

As Zaleha grew up in Malaysia and has been eating the dish since she was a child, you’d be forgiven for thinking that she knows exactly how the dish should be prepared.

However, Gregg Wallace – who is one of the show’s two male judges – immediately assumed an air of white male privilege.
