Royal Eggs

Taken all the way down to base materials, a batch of 3 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 19 units, plus 34 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 994 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 57 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.

Royal Eggs is itself consumed by 1 further recipe, all of them Culinarian recipes.
