It’s an argument that has circulated online for decades, and those on each side of the fence sit passionately. Milk or cereal first. For former sprint Olympian Harry-Aikines Aryeetey, there’s no question. Uploading a TikTok video pouring himself a bowl of Choco Wheaties, Aryeetey captioned the TikTok: 'Of course I pour my milk first'. 'Who's triggered? Don't hate me! Warm cereal for the win,' before adding '#milkfirstthencereal'. Weighing in on the debate is the founding director of the Centre for the Study of the Senses and professor of philosophy at the University of London, Barry Smith. Speaking with MailOnline, Smith explained that timing is key when it comes to how you make a bowl of cereal. 'Of course, it depends what the cereal is,' he said. 'The very earnest nuts and bolts granola from health food stores probably needs a good soak, while sugar-laden flakes may dissolve quickly.

'Everyone will have their preferred tolerance, and a little-known fact is how sensitive we are to texture and how much that affects food acceptability.

'Think of people who like their scrambled eggs runny, or firm, their meat well done or raw. We can put people on a scale and they will not be happy at the other end.' Smith concludes that while cereal will be better coated if the milk is poured over the top, if you’re after a crunch, cereal should come second.
