Do this.
1.) take your choice of food and put it next to you in a cup/bowl/etc.
2.) take a clove of garlic and shred it up over a cheese gratter(spelling) or crush it up.
3.) sprinkle a little all over a pan
4.) put the food of your choice on the tray
5.) sprinke some more ontop of the food.
6.) let it sit over night
7.) you have some nice food with garlic on it, now feel free to toss it in your tank and watch the results.
Spelling is so bad lol!
