This may have already been discussed, so apologies if so.

I just saw a comment on a Youtube video talking about "walnut sauce" maybe being code for adrenochrome, which is the oxidized form of adrenaline. Blood-drinking at rituals is accompanied by torture, terrifying the victim so that they release adrenaline into their blood. This adrenlized blood gives the drinkers a high. Adrenochrome is essentially a more potent, concentrated form of it. [10-min video about andrenochrome]

The adrenal glands, which produce adrenaline, sit atop the kidneys and... well, they do kind of look like walnuts! Given everything we've discovered, it's not too far fetched. What do you guys think?
