Culinarian's Apron ★

Taken all the way down to base materials, one Culinarian's Apron is 3 crafting steps deep and needs 6 intermediates — Undyed Felt ×2, Undyed Woolen Cloth ×2, Darksteel Nugget ×1 and 3 others — which resolve to 6 distinct raw materials totalling 20 units, plus 35 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,022 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 30 are burned by the intermediates, so the real crystal cost is 20 Lightning Shard, 6 Lightning Crystal, 4 Water Shard and 2 other kinds.

The chain crosses three disciplines — Weaver to Lv 50, Blacksmith to Lv 50 and Alchemist to Lv 25 — so no single class can finish it unaided.

4 of the 6 raw materials come out of the ground, and 2 of them are time-gated: Darksteel Ore (1:00) and Silkworm Cocoon (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Silk Thread has the widest use: 175 recipes call for it, spanning six of the eight crafting classes.
