Max Miller approves: a 3,770yo Babylonian clay tablet written in Akkadian, containing the oldest known cooking recipes. The tablet includes 25 recipes for meat and veggie stews. (recipes inside!)

As a feral Iberian
Huh! So you're on the Spanish / Portu Iberian peninsula, living a feral life? 😮
I remember reading about acorns in My Side of the Mountain, about a pre-teen boy who runs away and lives in the mountains for a season. IIRC acorns are really acidic, and need to be soaked, or something to get the tannins out in order to be edible. Those same tannins were evidently really handy for making leather, though.
In Medieval Europe, I believe there were also some leather preparation steps that involved urine and something else that smelled pretty darn foul. Gotta love the end-result, tho!
Ah, acorns... XD
