With the recipes verified so far, the best early Cauldron use is Plank → Oblivion Essence if you have a plank surplus, followed by Vitality Essence → Oblivion Essence for the pair of essences, because both build toward the late-game essence loop. Wood/plank production inside the Cauldron is a fun side path, not the main goal.
How to judge “best”
| Criterion | Question it answers |
|---|---|
| Input availability | Can you feed it steadily with what you already produce? |
| Output value | Does the output sell, feed research, or unlock chain content? |
| Achievement value | Does it progress a rare achievement? |

What to wait for
Community-claimed recipes (sulfur combos, “advanced cauldron” outcomes, fertilizer interactions) are unverified for 1.0. Until the formula table carries a badge, treat them as leads — the data standards page explains why we hold values back rather than guess.
The rule of thumb
Brew what you can feed steadily and what feeds the loop you are building. The Cauldron shines as a converter for surplus, not as a primary producer — except for the “make a plank with a cauldron” achievement, which is purely decorative.
