Rarefied Lemonade

Taken all the way down to base materials, one Rarefied Lemonade is 2 crafting steps deep and needs 1 intermediate — Golden Honey ×2 — which resolves to 4 distinct raw materials totalling 9 units, plus 21 crystals.

That bill outweighs 5,492 of the 13,602 recipes tracked here and 644 of the 1,058 Culinarian ones, and 4,464 recipes nest deeper.

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

Every step is Culinarian work, from a Lv 74 intermediate up to the Lv 80 finish, so one class covers the whole chain.

All 4 raw materials are gathered, and one of them is time-gated: Lemonette (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Golden Honey has the widest use: 12 recipes call for it, spanning two of the eight crafting classes.
