TEMPERATURE (°C)

And that's the science behind cookies!!

Water BOILS off at 100°C

the liquid raw batter starts to change into solid cookies

At 140°C, MAILLARD reaction happens.

Sugars and proteins in the batter start to combine and make delicious smells, tastes and the golden brown color .

At 180°C, CARAMELIZATION happens. 

The sugars combine to start making more delicious nutty caramel-y flavors with deeper brown colors.
