What, Where, When, Why?

I’ve unlocked all the recipes on my DS cooking mama, with only
a few to become gold or in whihc are silver and one bronze in the impossible octopus dumplings…now when i start the game gold utensils appear on the start screen. Also i have observed when choosing a recipe at the end, there are a range of fruit/vergetables. What are these meant to represent?

hope someone can help me
also, does anyone know what happens when every recipe has become ‘gold’ ?

thanks!
