Old Fishwife's Paella

Taken all the way down to base materials, one Old Fishwife's Paella is 2 crafting steps deep and needs 1 intermediate — Turali Corn Oil ×1 — which resolves to 6 distinct raw materials totalling 13 units, plus 24 crystals.

That bill outweighs 6,426 of the 13,602 recipes tracked here and 825 of the 1,058 Culinarian ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 8 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal and 8 Water Crystal.

Every step is Culinarian work, from a Lv 94 intermediate up to the Lv 100 finish, so one class covers the whole chain.

All 6 raw materials are gathered, and one of them is time-gated: Heavens Lemon (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Turali Corn Oil has the widest use: 16 recipes call for it, all of them Culinarian recipes.
