Connoisseur's Spaghetti al Nero ★★★

Taken all the way down to base materials, one Connoisseur's Spaghetti al Nero is 3 crafting steps deep and needs 4 intermediates — Garlean Cheese ×3, Perilla Oil ×3, Vermicelli ×2 and 1 other — which resolve to 6 distinct raw materials totalling 19 units, plus 37 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 994 of the 1,058 Culinarian ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 31 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 15 Fire Shard, 4 Fire Cluster and 1 other kind.

Every step is Culinarian work, from a Lv 52 intermediate up to the Lv 90 finish, so one class covers the whole chain.

4 of the 6 raw materials come out of the ground, and one of them is time-gated: Abalathian Rock Salt (10:00, 22:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Perilla Oil has the widest use: 31 recipes call for it, spanning two of the eight crafting classes.
