I am not sure if such thing exists in the USA but what you can see on the picture are sour pickles.
Basically this is how it's done:
Put water+pickles+spices+a piece of bread on the top into a glass jar.
Put it to a warm place (my mother put it into the sun) so it was at like 100F for 3-4 days then it gets sour and ready.
It was outside, uncovered.
Would it be safe to pitch into beer? Should i pitch it into fermented or unfermented beer?
Should i pitch the liquid or the white gunk on the top into the beer?
