Crafting
Two items in, one result out: what every pair makes, and everything a target item takes.

How this works: the game's crafting event puts the lower-numbered item first, then walks its recipe list in order and takes the first recipe with those two ingredients. It uses up one of each and gives the recipe's amount; with no match, crafting fails and nothing is used up. Each craft passes 15 minutes of game time. The plan follows the same recipes, makes the ingredients first, and uses up leftovers from earlier crafts before crafting more.
