Mayonnaise Machine output

One Golden Egg of any input quality is accepted by the local Mayonnaise Machine rule. After 180 in-game minutes it produces 3 gold-quality Mayonnaise. The input egg’s quality is not copied to the output.

  • Gold-quality Mayonnaise: 190g × 1.5 = 285g each.
  • Three jars without Artisan: 285g × 3 = 855g.
  • Three jars with Artisan: floor(285g × 1.4) × 3 = 399g × 3 = 1,197g.

Profession rule

Rancher does not increase Mayonnaise prices. Mayonnaise is an artisan good, so Artisan is the relevant sale-price profession. The old 1,026g total incorrectly multiplied 855g by Rancher’s 20% animal-product bonus.

Raw or processed?

  • Without professions, Mayonnaise (855g) beats regular, silver, and gold Golden Eggs but not an iridium Golden Egg (1,000g).
  • With Rancher, compare the raw egg column against 855g; gold and iridium raw eggs are worth more.
  • With Artisan, processed value is 1,197g, which beats every non-Rancher raw quality and nearly matches Rancher iridium at 1,200g.
