Kukuru Rusk ★★

Taken all the way down to base materials, a batch of 3 Kukuru Rusk is 2 crafting steps deep and needs 1 intermediate — Upland Wheat Flour ×1 — which resolves to 5 distinct raw materials totalling 12 units, plus 11 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 4 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 7 Fire Crystal, 2 Fire Cluster and 2 Water Cluster.

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

3 of the 5 raw materials come out of the ground, and one of them is time-gated: Ala Mhigan Salt Crystal (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Upland Wheat Flour has the widest use: 61 recipes call for it, all of them Culinarian recipes.
