From playing a brand new game to get this in Year 1 I selected the Meadow Farm at the start which gives chickens. Obtain a mayonaise maker either through the community quest or crafting. Keep your chickens happy all Spring and save a gold tier mayonaisse for the Luau on Summer Day 11. Achievement should pop when the Governor tastes the soup, be sure to add the gold tier mayonaisse before you talk to Lewis. Happy hunting reliving this classic game.
