Crumpet

Taken all the way down to base materials, a batch of 3 Crumpet is 2 crafting steps deep and needs 5 intermediates — Maple Syrup ×1, Natron ×1, Smooth Butter ×1 and 2 others — which resolve to 5 distinct raw materials totalling 11 units, plus 11 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 734 of the 1,058 Culinarian ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 7 Fire Shard and 4 Water Shard.

The chain crosses two disciplines — Culinarian to Lv 28 and Alchemist to Lv 25 — so no single class can finish it unaided.

4 of the 5 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Table Salt has the widest use: 51 recipes call for it, all of them Culinarian recipes.
