Chicken fat polynya

Okay, okay: it's just a bunch of chicken fat congealed over the juices I took from the pan I cooked some chicken thighs in.

I save that stuff for making rice or soups and so on. This is what yesterday's chicken fat looked like today before I threw the fat away and made rice with the liquid.

But it looks to me like an aerial photo of a lead in heavy ice, a polynya.
