Proper custom crafting table?

This is a bit of an important question for a mod I'm working on. But, does anyone know how to make a non-laggy, bug-less, crafting table? (Works alike to the normal crafting table, minus the recipe book and it's recipes) I was trying to make one with a lot of mod recipes and found it took a minute to go though all the recipes and sometimes bugged out and let me take out the result item multiple times. I guess I could do a check for certain slots and have a list of craftable items in a section under that. But, that's all I can think of. Any help is highly appreciated, thank you!
