Lactose turns milk from a universal cure into a compact per-player
survival system. Drinking milk builds a temporary reaction, repeated
drinking raises the danger, and recovery gradually improves tolerance.

Main systems

    • Separate reaction state for every player in singleplayer and multiplayer.
    • Reaction decay and recovery over time.
    • Anti-spam streak tracking for repeated milk use.
    • Tolerance and adaptation as players recover.
    • Optional challenge mode for faster escalation.
    • Lucky digestion, dairy disaster, and nearby-cow events.
    • A custom dairy advancement tree.
    • Player statistics and leaderboard commands.
    • Lactose-free milk and lactose-free cake recipes.


Play styles

    • /function lactose:config/soft — shorter, gentler reactions.
    • /function lactose:config/default — balanced default behavior.
    • /function lactose:config/spicy — louder and more dangerous milk mistakes.
    • /function lactose:config/challenge_on — faster reaction growth.
    • /function lactose:config/challenge_off — disable challenge mode.



Configuration commands are intended for operators. The selected configuration applies to the world.

Lactose-free crafting



Lactose-Free Milk is a shapeless recipe using a milk bucket, honey bottle, wheat, and sugar.


Lactose-Free Cake uses the normal cake layout: three milk buckets on
top, sugar around one egg in the middle, and three wheat on the bottom.
It is crafted directly at a normal crafting table; no crafting function
or inventory command is required.


The exact 1.21.11 recipe grids are included in the gallery.
