Ingredient Substitution
The recipe wants ‘some meat’, not one specific cut, so you cook with what's on hand.

No.042Don't Starve Together01The core loop
Action → feedback → next choice- 01Check category requirements

- 03Pick the cheapest substitute
- 04Get the dish and its variance
↻Feedback changes the situation — the next round starts from there.
Walk through one round
A simplified design example. Situations and numbers illustrate the mechanic, not exact rules from a reference game.
- T1
Turn 1 · The situation
A stew needs 2 meat plus 2 anything; the player has 1 large meat, 3 small meats, 4 twigs and 2 berries.
- T2
Turn 2 · The player chooses
They use 2 small meats for the meat value and 2 twigs as filler, keeping the large meat.
- T3
Turn 3 · The feedback
The stew succeeds, restoring 60 hunger, and the large meat survives for another pot tomorrow.
- T4
Turn 4 · The next decision
Had the meat value fallen short, they'd get useless mush, so they start noting each item's values.
How it plays
Recipes specify categories rather than exact items, like ‘any fish’, ‘at least one meat’ or ‘filler’. Players fill slots with cheap or surplus items and save precious ones; some systems vary quality or effect by substitute. The resulting dish, its stats, or a failed product are the feedback.
What the player weighs
- Use cheap substitutes to save resources, or premium ones for a better dish.
- Assemble a known result, or test an uncertain combination.
02Start small
Scope is an editorial estimate for the minimum prototype, not the reference game or a production schedule.
03One mechanic, different implementations

Don't Starve Together
The Crock Pot judges recipes by values like meat, vegetable and fruit content, with twigs or ice usable as filler, so substitution is the core play.

Stardew Valley
Most recipes need specific items, but some accept categories like any fish or any egg, letting players use up common surplus.
The difference worth noticing
Don't Starve Together builds its whole cooking system on substitution; Stardew Valley offers limited flexibility in a few recipes.

04What could you combine?
Have customers order by description (‘spicy, chewy’), so players decide which substitutes satisfy the request.
