Villagers favorite foods

Especially in the beginning I loved cooking all the different foods in Minecraft, but as you play more and learn what the most optimal foods are, all the other recipes lose their value and become uninteresting.

It's a simple way to give new life to all the food recipes Minecraft has to offer by attaching a practical use to them
