Sweatcorn

Sweatcorn is a cultivated crop in Oxygen Not Included used primarily as animal feed and as a raw ingredient in high-calorie recipes. It appears as a farmable plant that produces edible kernels; the item is stackable and handled like other cooked/raw foods in the game's supply and storage systems. Sweatcorn is notable for its use in both livestock production and in cooking recipes that restore large amounts of calories.

Sweatcorn is commonly fed to Hatches and Sage Hatches to produce Coal. Feeding Sweatcorn to these creatures converts biological food input into a stable fuel resource, making Sweatcorn an integral part of early- to mid-game fuel loops when players want a renewable source of coal. Sage Hatches likewise accept Sweatcorn; the resulting coal yield is useful for fueling generators or other coal-consuming buildings.

In addition to being animal feed, Sweatcorn (and Pikeapple) is an ingredient for a Smoker recipe that yields a high-calorie cooked food. The Smoker recipe uses 5,600 kcal worth of Sweatcorn or Pikeapple to produce a cooked meal that restores +11,450 kcal and grants +2 quality. This recipe is described as crisp vegetables stuffed with herbs and smoked for hours, making it one of the more calorie-dense cooking options suitable for sustaining duplicants.

Practical notes and interactions:

• Use dedicated crop farms with irrigation and fertilization to grow Sweatcorn efficiently; manage harvest schedules to maintain a steady supply for both hatches and cooking.
• Prioritize feeding Sweatcorn to Hatches when you need coal; stockpile raw Sweatcorn near livestock pens to minimize travel time for duplicants.
• Reserve Sweatcorn for cooking only if duplicant morale/food quality requirements or long-term calorie needs justify its consumption rather than converting it into coal.
• The Smoker recipe consumes a large calorie bundle (5,600 kcal per batch) but returns an even larger cooked calorie amount, making it a net-efficient way to convert raw plant calories into durable cooked food if you have the Smoker and sufficient ingredients.
