The furnace chooses the used recipe by itself (it uses the recipe with the right input item). This behavior can be used to furnace, depending on what is currently needed/coming in.

Note, that this strategy is quite advanced, cause the inserters will fill normally the furnace up to 5 items, so especially when the output is blocked (cause too much produced) you cannot input (the more needed) item.

Quick summary

Furnaces are used to smelt resources into usable products for further usage. This makes them a key building for development and automation. Starting with very basic stone furnaces the player can advance through research and replace them with more efficient and faster furnaces later in the game.

Furnaces with module slots are affected by beacons. Currently this is only the case for electric furnaces.
