Wondering whether Sumerian zid-lal3 was something like خبيص (khabeeṣa), which was served in cups to gods and mentioned with morning meals:

[ZID3] Flour, often emmer or semolina

[LAL3] Honey, syrup

We don't actually know what Mati-belum said to Nidnat-Sin to get up him this upset, but it's fun to imagine.
