High House Supper Set

Taken all the way down to base materials, one High House Supper Set is 4 crafting steps deep and needs 14 intermediates — Fig Bavarois ×1, Royal Eggs ×1, Sauteed Porcini ×1 and 11 others — which resolve to 21 distinct raw materials totalling 49 units, plus 82 crystals.

That bill outweighs 12,749 of the 13,602 recipes tracked here and 1,052 of the 1,058 Culinarian ones, and 1 recipe nests deeper.

Only 9 of those crystals go into the final step; the other 73 are burned by the intermediates, so the real crystal cost is 38 Fire Shard, 25 Fire Crystal and 19 Water Crystal.

Every step is Culinarian work, so one class covers the whole chain.

One intermediate outranks the result: Royal Eggs is a Lv 57 Culinarian recipe feeding a Lv 56 craft, so that step, not the last one, is the real gate.

13 of the 21 raw materials come out of the ground, and 4 of them are time-gated: Old World Fig (2:00, 4:00, 14:00, 16:00), Heavens Lemon (6:00, 18:00) and 2 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.
