This cheat allows you to use a spice even if you don't have it. To do this you need at least one type of spice. On the spice selection screen use the D-Pad and highlight the spice you need that you're out of. Then using the stylus/touch screen highlight a spice you do have, then press A. If done correctly the spice you want to use that your out of will go from 0 to -1 and appear in the box of spices being used on the top screen.
