The Chemistry of Weakness

Bacon makes you stop whatever you’re doing. Not because you’re hungry—you might not be hungry at all—but because something in the smell bypasses rational thought entirely and lands directly in whatever part of the brain handles desire. The pan goes on and the negotiation is already lost.

The reason is mostly chemistry: the Maillard reaction, which is what happens when amino acids and reducing sugars meet heat and start generating hundreds of new flavor and aroma compounds at once. Add bacon’s high fat content—rendering and oxidizing as it cooks—and you get something that hits almost every register simultaneously: savory, sweet, smoky, something almost caramelized underneath. No single smell, just a convergence of them, all pulling in the same direction. The fact that it arrives before the food does only makes it worse. By the time the bacon is actually ready you’ve been negotiating with your own appetite for three minutes, and you lost at the start.

Cucumbers don’t do this. Yogurt doesn’t do this. Cornflakes are particularly inert in this regard. Bacon is operating at a different level, and having a scientific explanation for it doesn’t make it any less humbling to be subject to.
