Because a dark color (such as black) would absorb more heat from the sun

A solar cooker and a pressure cooker are two completely different ways of cooking. A pressure cooker can still use a heat source like a gas or electric cook top. A solar cooker is as the mercy of the heat of the sun and the contents will only cook as well as the amount of heat it obtains.
2 hours
you can use aluminum foil
You can heat things (for example, use a solar system to heat water, and use it to take a shower - or use a solar cooker to cook food), and you can generate electricity from the Sun's energy.
When sunlight falls over the solar cooker top, the sun rays pass through the glass sheet cover and get absorbed inside the cooker box. This glass sheet covers does not allow the solar energy to flow out in the form of radiant heat.Thus it traps more and more heat rays of the sun thereby producing green house effect.That is why glass lid is used in the solar cooker.
concave mirror are the best as it collects the sunlight coming from infinity to a single point called focus.it produces intense heat to cook food easily.still using plane mirror on household level for solar cooker is foolishness.
