This one i don't really know... a buffer? i'm guessing it would have to be something pretty neutral... lemon juice is acidic, i don't know if blood is neutral but i imagine curd is...
OpenStudy (anonymous):

OpenStudy (agent0smith):
that answer supports blood... i guess blood kinda makes sense.
OpenStudy (anonymous):
Oh.. Blood ._. .. Huh.
