A small set of blends, each documented to a printed profile: exact gram ratios, the toast, the grind, and the aroma compounds that carry it. Cuminaldehyde for cumin's earth, eugenol for the heat of clove, cinnamaldehyde for the sweet edge of cinnamon.
Start with the named blends: a Levantine seven spice, a Japanese curry powder built from toasted whole spices, and the fish and rice mixes that season a Gazan sayadiya.
Fewer blends, each explained. When a mix earns a place here it arrives whole: what goes in, in what ratio, and which molecule you are actually smelling.
Japan's first written mention of curry is an entry in an 1860 phrasebook; the first Japanese man on record to meet it called it filthy. A century and a half later the country eats it more than once a week. The path runs through a British spice tin, a navy cookbook and a bar of roux.
Laurus nobilis is on the FDA's safe list and in nearly every stock pot on earth. The leaf still comes out before serving, for a reason that has nothing to do with poison, and the poisonous plant people are thinking of is a different tree.
An American ethnographer watching Palestinian villagers in 1921 wrote down the dish and the reason for its name in one sentence. What the record actually holds before that, what is folklore, and the starch, oil and browning that let a pot of rice stand up on a platter.
