Duck Mayonnaise

Duck Mayonnaise is an Artisan Good made by placing a Duck Egg into a Mayonnaise Machine, which takes 3 hours to produce. Like other mayonnaise products, it is a processed animal product rather than a raw farm item, and it can be made as soon as the player has both a Duck Egg and access to a Mayonnaise Machine.

Duck Mayonnaise has a few special uses, but it is otherwise a fairly straightforward item. It is not used in any bundles, recipes, or quests, so its main value comes from sale, tailoring, and a single secret interaction. In the Sewing Machine, it can be used as a white dye when paired with a dyeable clothing item. It is also used with Cloth in the Sewing Machine, though the resulting garment is not specified in the available source material.

A notable secret use exists in The Stardrop Saloon: if Duck Mayonnaise is placed in the partially hidden purple box in the back room, the player receives a Pinky Lemon statue. This makes Duck Mayonnaise one of the few Artisan Goods with a hidden exchange tied to a specific location in town.

In practice, Duck Mayonnaise is most useful when the player has a steady supply of Duck Eggs and wants to turn them into processed goods. Since it does not participate in progression systems like bundles or quests, it is best treated as a crafting and profit item unless the player is aiming for the saloon secret or tailoring use.
