Why use a kitchen torch to melt the cheeses? Couldn't they have been melted in the oven? Sure, that's an option. If I were cooking a whole tray of fishballs a la Parmigiana, that's what I would have done. But we're talking three fishballs here. THREE. Waste of time and electricity to preheat the oven only to melt the cheeses on top of three fishballs. So... kitchen torch.
