Mysterious Liquid

I found a bucket of yellow liquid in my refrigerator the other day. As I stared at it in deep preponderance of thought, I wondered if the liquid was urine or melted butter. I thought about tasting it to resolve my query, but decided against it because of the unsavory nature a possible libation of urine would bring. Instead I decided to grease a pan with the substance before cooking some stir fry.

My residence smelled like burnt urine for several days.
