Why do marshmallows turn brown?
Heat transforms sugars through caramelization. Maillard reactions between reducing sugars and amino compounds can also contribute, depending on the recipe. The golden surface is a record of heat exposure.

THE SCIENCE OF TOASTING
There’s wonder in the warmth.
How to roast a marshmallow evenly
A surface facing the fire receives more radiant heat. Turning the skewer shares that exposure around the marshmallow. Try moderate heat, a little distance and a steady rotation.
Golden outside. What about inside?
The center warms more slowly as heat moves inward. A dark crust does not guarantee a soft center. Gentle roasting gives warmth time to travel, and residual heat keeps working after removal.

A FEW FIRESIDE QUESTIONS
A little guidance for the glow.
How do I play?
Press Light your moment. Adjust heat, distance and rotation, then finish when the surface looks right. Drag up and down on the scene to move the skewer, and sideways to turn it.
How is my score calculated?
Evenness is worth 40 points, closeness to the golden target 25, center softness 20 and removal timing 15. The twelve zones accumulate heat independently; a motionless skewer can burn one side while leaving the other pale.
Can I play on mobile or with a keyboard?
Yes. Use touch sliders or drag the scene. With a keyboard, use Tab to select a control and arrow keys to adjust it. Reduced-motion preferences are respected; sound is off until you choose it.
What is Blind Roast?
Surface status and the timer are hidden during roasting. Judge the color with your eyes; your controls and final passport still work normally.
