Why Stardew Valley Players Should Hold Off on Making Dinosaur Mayo

gamerant.com:

Stardew Valley update 1.6 has introduced a way to make Dinosaur Eggs more valuable than Dinosaur Mayonnaise. While doing so requires some legwork, Stardew Valley players may still want to hold off on making any more Dinosaur Mayo if they're looking to maximize the fruits of their labor, profit-wise.

Dinosaur Eggs have been part of the hit farming sim since its 2016 release. However, they had initially only produced gold-quality Mayo when placed into a Stardew Valley Mayonnaise Machine. This all changed with the November 2019 release of the game's 1.4 update, which introduced Dinosaur Mayonnaise. Despite not having quality levels like its original counterpart, Dinosaur Mayonnaise sells for more than even iridium-quality mayo.

But even this valuable commodity has now been outclassed following the release of the game's latest patch. As recently noted by Reddit user jessipoo451, reading the Treasure Appraisal Guide permanently triples the price of Dinosaur Eggs, making even their worst-quality variants more valuable than Dinosaur Mayonnaise. Obtaining this Stardew Valley skill book thus essentially renders Dinosaur Mayo irrelevant for anything but completing specific (re)quests.

The difference is also fairly significant, as the Treasure Appraisal Guide makes regular Dinosaur Eggs sell for 1050 gold, nearly 32% more than Dinosaur Mayo. Meanwhile, selling iridium-quality eggs is 162.5% more profitable than turning them into mayonnaise after obtaining the skill book. Doing so isn't particularly difficult, as the guide can be found in both Artifact Troves and Mystery Boxes. But the easiest way to procure it is to simply purchase it from the Stardew Valley Bookseller, which appears twice a season.
