The ingredient ratios are the Yale researchers' interpretation—they're not from the source text,

> "Like most premodern cooking manuals, the Babylonian recipes rarely list the quantities of each ingredient, and so basic experimentation is needed to determine viable proportions for the assembly of a dough or the salting of a stew. The “experimental” approach likewise offers answers to questions that can only be addressed through trial and error. For example, many of the identifications of herbs proposed by modern scholars are based mainly on medical compendia, and some of the plants thus identified can produce an extremely bitter or perhaps pungent taste when used in food."
Here's the recipes as literally translated (I used tesseract to OCR):
> "Unwinding. Meat is not used. You prepare water. You add fat. (You add) kurrat, cilantro, salt as desired, leek, garlic. You pound up dried sourdough, you sift (it) and you scatter (it) over the pot before removing it."
> "Stew of lamb. Meat is used. You prepare water. You add fat. You add fine-grained salt, dried barley cakes, onion, Persian shallot, and milk. [You crush] (and add) leek and garlic."
> "Elamite broth. Meat is not used. You prepare water. You add fat. Dill, kurrat, cilantro, leek, and garlic bound with blood, a corresponding amount of sour milk, and (more) garlic. The (original) name (of this dish) is Zukanda."
> "Tuh’u. Leg meat is used. You prepare water. You add fat. You sear. You fold in salt, beer, onion, arugula, cilantro, Persian shallot, cumin, and red’ beet, and [you crush] leek and garlic. You sprinkle coriander on top. [You add] kurrat and fresh cilantro."
