How do I disable SP spawning

[Rexxae]

Hey there, I can spawn items in simgleplayer by pressing the icon in NEI. (Most of you prolly can)

And I looked around here for a while, and I cant seem to find a solution. I even made an account to ask this :3

But the question mostly is in the titel, so lets stop typing useless words.

Open inventory, Press O.

Or if you still want NEI:

Open inventory, options, turn to recipe mode.
