Skimmed Milk

Thirst is what it is good for. Its own text calls it hydrating but less calorie dense than whole milk, so it sits between water and a meal: strong on the thirst bar, weaker on the food one.

Nobody sets out to make it. It is what remains when milk separates in a fridge and the part you wanted was the cream. Say your group just turned a stack of milk into cream for creamy teas before a raid. The fridge is now full of skimmed bottles nobody planned for. No recipe asks for it, so drinking is its only job.

Do not throw it out. Keep a few in the hotbar on a farm run or hand them to whoever holds the walls during a defence, and you save trips to the river. On long trips a small water bottle is still handier, since you can refill it.
