That's what im saying. Always show the recipe and if the player adds more than the 1x recipe, 20 coffee in this example, then it ups the other 2 values to match the ratio.
Then they always know exactly how much of each they need to add and if they need to add more.

You'd only be able to base that ratio on the first ingredient, i imagine.
Have i got the correct end of the stick?
