How to get the crafting recipes in minecraft?

I've seen some youtubers like thediamondminecart and when he does a mod review, he shows the crafting recipes in a gui in the screen. I want to know if this is part of the game or a mod. Please tell me how to work it also.

The mod is called "Not Enough Items", "Too Many Items" doesn't show the recipes.
