The Chemistry of Food & Taste | Dr. Harold McGee

Traditional Methods

Traditional fermentation methods have been a cornerstone of culinary practices across the globe, including the Arctic regions where foods like "stink fish" are highly prized. Harold McGee explains that fermentation was likely discovered by observing natural processes, such as overripe fruits fermenting on the forest floor 1. This method requires minimal intervention, often just burying the food, which then develops unique flavors and textures.

Fermentation has been discovered essentially by every population on the Earth, including the Arctic, where you think it might take a while for things to go on, but in fact, products that are translated into English as stinkfish are among the most prized of the foods in the Inuit regions of the Pole.

Cheese, another product of fermentation, showcases human ingenuity by transforming basic ingredients into a diverse array of flavors. McGee shares his experience in France, where he learned about the vast diversity of cheese, which has been made since the early domestication of animals 2.

   

Modern Innovations

Modern innovations in fermentation are reshaping the culinary landscape, introducing new foods that challenge traditional palates. Harold McGee notes that traditional food materials are now being transformed by microbes in novel ways, leading to exciting new culinary creations 3. This evolution is not just about returning to ancient methods but also about creating new hybrids of foods that offer unique flavors and textures.

We're now seeing how traditional food materials can be transformed by the action of microbes that we kind of know about, but only know about in very specific contexts.

The art of wine and cheese making exemplifies this innovation, where variations in production lead to a wide range of flavors. McGee emphasizes that a deeper understanding of these processes enhances appreciation, much like in other art forms 4.
