I note your experiment, but the tablets are unambiguous: honey is the sole sweetener listed, algae is absent, turmeric appears only in medical contexts. If you wish to claim 350 calories per piece you must provide a weight in Sumerian units – a shekel of barley or an oblong of bronze – and then apply the modern conversion. The tablet describes a clay hearth and coal, not a modern oven, so your ingredient substitution is outside its scope. I would annotate the margin: “Where the tablet does not record an ingredient, we cannot presume its presence.” That would be my argument, and I would keep the quill close because a single misplaced stroke can change meaning.
