Same dish combo??!

CAN SOMEONE PLEASE TELL ME WHAT YOU NEED TO DO TO GET A "SAME DISH COMBO"?!!?!?!!
It would be nice if there was some type of explanation for the goals you need to complete on each level. The "same dish combo", for example, apparently isnt as obvious as you would think and without a help screen to spell it out you basically have to just keep repeating the same level over and over hoping to luck out. Very frustrating. Add this issue to the extremely slow and consistently glitchy game in general and it becomes more irritating than entertaining.
