Rarefied Marron Glace

Taken all the way down to base materials, one Rarefied Marron Glace is 2 crafting steps deep and needs 1 intermediate — Birch Syrup ×3 — which resolves to 3 distinct raw materials totalling 6 units, plus 19 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 531 of the 1,058 Culinarian ones, and 4,464 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 8 are burned by the intermediates, so the real crystal cost is 8 Fire Shard, 6 Fire Crystal and 5 Water Crystal.

Every step is Culinarian work, from a Lv 59 intermediate up to the Lv 60 finish, so one class covers the whole chain.

1 of the 3 raw materials matches a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Birch Syrup has the widest use: 13 recipes call for it, all of them Culinarian recipes.
