Ways to celebrate

Nearly every baking recipe starts with the same instruction: preheat to 350 degrees. That's not an arbitrary round number — it's the temperature where real chemistry kicks in.

Learn the science behind the golden crust

At around 350°F, amino acids and sugars in your ingredients begin the Maillard reaction — the same browning process behind a seared steak, roasted coffee, or toasted marshmallow. It's actually many small simultaneous reactions, which is why baked goods develop such complex flavors and color.

Meet the chemist behind the name

French chemist Louis Camille Maillard first described the reaction in 1912, though it took until 1953 for USDA chemist John Hodge to work out its exact mechanism. Read the fuller explanation of why this one chemical reaction defines so much of what makes baked food taste good.

Put the science to work

Bake something today and pay attention to the crust — cooking temperature, time, and moisture all shift how much browning (and flavor) you get.
