This is a very easy way to render out fat from chicken skin using a microwave. In ramen terminology, this is called, "Chiyu" and its a very popular base for aroma oils. You can take this and infuse it with other aromatics like green onions, garlic and ginger, or just use it straight. Store in the fridge for a few weeks or the freezer for a few months.

I think this method also works to make lard using pork fat but I haven't tried yet.
