Paella

Taken all the way down to base materials, a batch of 3 Paella is 2 crafting steps deep and needs 1 intermediate — Frantoio Oil ×1 — which resolves to 6 distinct raw materials totalling 12 units, plus 20 crystals.

That bill outweighs 6,221 of the 13,602 recipes tracked here and 773 of the 1,058 Culinarian ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 13 Fire Crystal and 7 Water Crystal.

Every step is Culinarian work, from a Lv 71 intermediate up to the Lv 79 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, Frantoio Oil has the widest use: 35 recipes call for it, all of them Culinarian recipes.
