What are ultra-processed foods and why are they coming to get me?
Anyone with even a cursory interest in food and nutrition must have noticed that ultra-processed foods are having a big moment in the media. Barely a day goes by why without some article like “Every Bite of Ultra-Processed Foods May Increase Risk of Early Death, Study Says” or “Ultra-processed foods are silently altering your metabolism, Continue reading

Everything you ever wanted to know about cream (the food not the band)
Today I want to get back to dairy. In particular I want to get back to milks sexy cousin: cream. Cream comes from milk and we already know that milk is an emulsion of fats dispersed in a watery continuous phase. We also know that the fats in milk are packaged into a globule called Continue reading

Everything you think you know about nutrition is probably wrong
Are you confused about what we should be eating? Bewildered by contradictory dietary advice? Overwhelmed by dietary fads and loud-mouthed influencers? Well you are not alone. Over the past five decades endless cycles of contradictory nutrition advice and dietary fads have left most people in a state of utter confusion about what constitutes a healthy Continue reading

Quick Bite: How salt enhances the flavour of our food
In my recent post on MSG and our taste perception I was going to include a bit about salt and how it works as a flavour enhancer but, as usual, I went on a bit so I couldn’t fit it in. So I wanted to do this short post while it was all fresh in Continue reading

The science behind umami: Understanding the way we perceive taste
Most of us have now heard of umami and we probably all know that umami is now recognised as the fifth of our primary tastes, formerly limited to sweet, sour, bitter and salty. You might also know that Western societies were a bit slow to the umami party. Despite being recognised in the East for Continue reading

Starch and Gelatinisation in Everyday Cooking
I’m no historian but I think it would be fair to say that for most of history most humans relied primarily on starchy grains and vegetables to keep themselves and their families fed. Grasses like wheat, rice, oats and barley are easy to grow and the seeds, or grains, of these grasses are rich in Continue reading

Pasteurisation, food safety and raw milk
I like milk but, lets face it, the rear end of a cow is a pretty grotty place. You’ve got the business end of the alimentary system, a tail swishing around spreading manure all round the place and the udder, the source of our milk, is right there in the middle. Cows aren’t great at Continue reading

Milk: Nature’s Beverage and Its Curious Chemistry
I think humans have an interesting relationship with milk. Most of us start our food journey with human breast milk yet many, long after we’ve out grown any biological need for milk, chose to consume the milk and milk products of other species. To support this we have set up a $800 million dollar a Continue reading

Coffee I: The science behind the buzz
If you’ve ever been in a coffee shop in the 21st century you’re familiar with the scene; people on laptops, headphones on interacting online while sipping their latte, cappuccino or piccolo. I’m certainly not condemning this behaviour, and have done the same many times, but what strikes me is a weird sense of continuity, a Continue reading

Are eggs bad for science?
The primary aim of this blog is to become a better home cook by learning some of the science of cooking. But I do have a secondary aim and that is to occasionally talk about how science works in the context of food science. This week is the first week I’ve really focused on how Continue reading

Fermentation I: Beer and chemistry
I had a long break over Christmas and these are a few of the meals I had during that break: at the local pizza joint a pepperoni pizza washed down with beer, a trip to the German club where I had a pork knuckle with sauerkraut washed down with beer, a trip to a French Continue reading

Quick bite: A cooks tour of fats and oils, the good, the bad and the ugly
In my last post on emulsions I was a pretty loose with my terminology when referring to fats, oils, lipids, cholesterol etc. In this Quick Bite I just want to explain some of the terminology and start getting a bit more precise about what I mean when I say ‘fat’ (or an oil which is Continue reading

Understanding Emulsions II: Mayonnaise
In my mind mayonnaise has always been kind of a Jekyll and Hyde sauce. We all know what mayonnaise is and we all have a bottle of mayonnaise in the fridge. But we also have homemade mayonnaise, a sauce that can be richer tasting but which can also vary greatly depending on what oil and Continue reading

Mastering the science of sugar: From simple syrups to caramel
I’ve been catching up on the latest series of the Great British Bake Off and in one episode, amongst all the usual drama of collapsing pastries and sagging cakes, the contestants were overcooking their caramel for the Banoffee Pie technical and it made me think about sugar. In recent posts I’ve talked a lot about Continue reading
