Mayonnaise Maker (FoMT)

The Mayonnaise Maker is a special tool in Harvest Moon: Friends of Mineral Town and Harvest Moon: More Friends of Mineral Town.

In order to get the mayonnaise maker, you must first upgrade your chicken coop in order to make room. In the Spring Mine, levels 10 and below, you can mine up Adamantite and give the ore and pay a fee of 20,000G to Saibara.

Once it's built, you can put any quality egg into it to produce mayonnaise of the same quality. This allows the player to gain more profits, as mayonnaise is more expensive than eggs.
