TL;DR
In the entity info window on the right show what ingredients a recipe has and what it lacks.What ?
The entity info should look something like this:Ingredients that are completely lacking should appear ghosted. Ingredients that are present but in insufficient number should have their number shown as red.
More colors could be used. For example yellow could indicate a sufficient amount for one cycle but not the requested amount.
Also results could be shown as ghosted when none are present to avoid the window constantly resizing when items are build and near instantly removed by inserters.
