Wait what, you're out here cooking with old forgotten spices? That sounds like a recipe for dust soup lmao.

Hearing "concrete block"... I had a similar mess with a gallon of sweet tea left in my trunk last summer. It fermented and swelled up so bad the plastic jug deformed... ended up with a sticky, rock-hard mass I had to scrape out for days. The smell was something else entirely.

Who would've thought @olivia799's food data point could change my view?
