How do you configure leftover items when crafting something?

I'm planning on making a crafting recipe that consists of an input of a water bucket, a custom-made "Salt" item, and a custom-made "Bottle of Air" item to give a bucket of something in the output; however, I want to leave behind within the input boxes just a glass bottle. When I tried this, not only did the glass bottle not appear, but (due to Minecraft's existing code) only a bucket was left behind in the place of the previous water bucket. Is there any decently simple way of only leaving behind certain items when crafting an item?
