Thermoses

Hear me out. Thermoses that can hold several bowls of soup. 

Using potion buffs on a regular basis has been harder ever since blaze powder was required to make potion buffs. But suspicious stew would be a pretty cool alternative if it didn't take up so much space and the buffs lasted longer. 

Thermoses could be used to increase the buff with enchantments and it could hold several soups in one slot. It could also be used to hold potions or several buckets of water/lava because of Minecraft logic. 

This could also be used as an opportunity to make farming more useful by mixing crops to make soups for different buffs. 

It doesn't have to be a thermos, just having better soup and more uses for crops would be cool.
