oven details

Modes in oven
1.microwave
2.grill
3.convection

1.microwave
uses wave properties to vibrate food molecules and generate heat,and thus it cooks the food
inside out.cannot use to toast bread, toasting needs only the surfaces to be heated

2.grill
resembles traditional cooking
1.direct and indirect grill
one with lid open,other with lid closed
the coil used to heat mostly is on the top side, traditional cooking fire and bottom of the food are closer, in oven grill the coil and top of the food is closer

3.convection
grill + fans
grill cooks the food closer to the coil first, because the temperature is more at the top
convection uses fans to distribute the hot air evenly and thus cooks all the surfaces evenly
