Rarefied Royal Eggs

Taken all the way down to base materials, one Rarefied Royal Eggs is 3 crafting steps deep and needs 5 intermediates — Hollandaise Sauce ×1, Ishgardian Muffin ×1, Sunset Wheat Flour ×3 and 2 others — which resolve to 8 distinct raw materials totalling 20 units, plus 34 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,010 of the 1,058 Culinarian ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 25 are burned by the intermediates, so the real crystal cost is 18 Fire Shard, 9 Fire Crystal and 7 Water Crystal.

Every step is Culinarian work, from a Lv 7 intermediate up to the Lv 56 finish, so one class covers the whole chain.

5 of the 8 raw materials come out of the ground, and one of them is time-gated: Heavens Lemon (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Fermented Butter has the widest use: 32 recipes call for it, all of them Culinarian recipes.
