Gelatin

Nothing in this list is craftable in turn, so a batch of 5 Gelatin is a single step: 2 units of material drawn from 2 base items, plus 1 crystal.

That bill outweighs 3,130 of the 13,602 recipes tracked here and 392 of the 1,058 Culinarian ones, and 9,374 recipes nest deeper.

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

Gelatin is itself consumed by 14 further recipes, all of them Culinarian recipes.
