A convection oven, we call that "Umluftherd" in German.
The US design for such household ovens always had me wondering. When the pans are in flames and the pots are burning, you have to reach through the heat and smoke and flames to get to the buttons, isn't that impractical?
Ours have the buttons and things at the front, and below the heating areas. So when the soup cooks over and the milk is up in hot foam, you have to grab a turning button with cooking hot cream on it - maybe not any better...
Cooking is dangerous business. Better let cook and have somebody else going up in flames.
now I know why so many men nevertheless get married. Maybe its more clever than I initially thought...
