The Mayonnaise Maker is a special tool in Harvest Moon: Back To Nature.

After upgrading the Chicken Coop (from the Woodcutter's House), Saibara will sell the Mayonnaise Maker at the Blacksmith. It costs one Adamantite ore and 20,000G, and will take 5 days to build.

The Mayonnaise Maker is able to convert Eggs into Mayonnaise. The size of the Mayonnaise is determined by the quality of the Egg that was added. Adding a Golden egg to the Mayonnaise Maker creates Mayonnaise G (Golden mayonnaise). Mayonnaise sells for a higher price compared to Eggs.

Item Value Quality of Egg Used
Mayonnaise S 100G Normal
Mayonnaise M 150G Good
Mayonnaise L 200G Excellent
Mayonnaise G 300G Golden egg
