so i know the new version has a cook book, and my goal was to make burgers. 

Put water in a bucket, used flour and got dough, cut the dough with a knife which made buns. 
put the buns on the hot plate and they cooked. 

Cut the steak with a knife and got patties, put them on the hot plate n got cooked patties. 

So i cut the tomato into slices, but the book says cook them? It just lights on fire and doesnt cook. 

I bought cheese from the store but the knife doesnt seem to cut it, and i cant cube or slice the cheese, and without it i cant make a burger. Am i dumb?
