In the wild of Land's End, in the dark heart of Golden Gate Park, and in hundred other locations, grows a strange, circular leaf.

We call it: Miner's Lettuce.

People who speak Latin, or wear Lab Coats call it: Claytonia Perfoliata

It grows everywhere across California's Coast, and I've used it to supplement meals while camping, or just to gnaw on whilst on the trail. It's named for the miners of California's past, who ate it to get vitamin C and prevent scurvy. It can be eaten raw, boilied like spinach, or made into a simple salad, and it tastes similar to spinach, with a fleshier, thicker texture.
