Cheese on toast is a simple concept but easy to get wrong.
Thick-cut bread
Firm-fleshed strong-flavoured cheese, grated
Toppings (e.g. pickles, onion, walnuts, etc.)
Toast one side of the bread under a medium broiler.
Lightly toast the other side of the bread, just enough to warm it, then spread the grated cheese over it. Add desired toppings.
Broil the cheesy side of the bread until the cheese is bubbling and brown.
Eat quickly, but be careful, as the cheese will be tongue-burningly hot!
