my favorite depression meal is an easy rice and beans. buy those flavored rice sides that come in a bag, chicken flavor is a good default option. cook it per instructions, then throw in a drained can of black beans and whatever frozen veggies sound good. don’t even bother heating up the beans or veggies, there’s enough heat in the rice that everything ends up nice and warm. just give it all a stir and you’re done.
the rice sides have enough flavor to make everything taste good as is, but there’s definitely room to toss in whatever spices are within arms reach that sound good.
The original post only gave half the explanation. It’s not that lead exists in general, it’s that lead exists within zircon crystals.
Under normal circumstances that would be impossible, zircon crystals strongly reject lead atoms as they form. There’s no way to stuff lead into the crystal lattice in the quantity we find them there. But uranium and zircon go together just fine, we just have to wait for it to decay into lead. The trouble is it takes ~4.5 billion years for just half of those uranium atoms to turn into lead. So any zircon crystal we find with half as much lead as uranium must be roughly that old
