Tortilla Press

Taken all the way down to base materials, one Tortilla Press is 2 crafting steps deep and needs 3 intermediates — Lar Ingot ×1, Mountain Chromite Ingot ×1 and Ruthenium Ingot ×1 — which resolve to 6 distinct raw materials totalling 18 units, plus 39 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 781 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 24 Fire Crystal, 8 Wind Crystal and 7 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 93 and Goldsmith to Lv 91 — so no single class can finish it unaided.

All 6 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Lar Ingot has the widest use: 101 recipes call for it, spanning six of the eight crafting classes.
