Automatic hot dog cooking grill

[Moby Duck]

Great machine I like it, but I have some doubts about whether these Frikandels are being actually cooked or just charred by the coals.

Where I come from American Hot Dogs are boiled, not grilled, as are several other red/brown skinned sausages called Frankfurters, Saveloys, Polonies, Cherios etc.
(We call a Frankfurter in a long bread roll an American Hot Dog, whereas an ordinary sausage, lengthwise on a stick, dipped in batter and deep fried is a Hot Dog).
Sausages are grilled or fried in a pan, but the best way to achieve even browning is to bake them in a pan in the oven. Give it a try, even cooking, even brown colour all over, and no charred burnt spots.
I note that the American spell checker doesn't recognise, Saveloys, Polonies, Cherios, but I am sure that you will have their equivalents.
I have also been told that if you were to post a clip on how the likes of Frankfurters are made, many viewers would never eat them again.
