The Maillard Reaction

cooking chemistry · food science · browning

Searing makes flavor. When you cook a steak really hot, the heat makes amino acids and sugars react with each other, turning the outside brown and creating that amazing savory taste you love.

It happens everywhere. Cookies getting golden, toast turning brown, marshmallows charring at a campfire, and falafel frying all use this same chemical reaction to build their delicious flavors.

Heat is the key. The Maillard reaction usually starts around 280 degrees Fahrenheit and works best up to about 330 degrees, which is why recipes tell you to use high heat for the best browning.

Named after a scientist. A French chemist named Louis Camille Maillard discovered this reaction in 1912 while trying to figure out how proteins work in living things.

Creates new compounds. The reaction makes special brown molecules called melanoidins that don't exist in the raw food before you cook it, which is why cooked food looks and tastes so different from raw.
