I have 3 things that I use the most in the kitchen. Not always for cookies, but I use these items EVERY day!
1) Measure all cup (I actually want a second one)
2) Prep Bowl Set (6-1 cup glass bowls with lids, these are full ALL The time, for snacks, prep work, small serving dishes for toppings, etc... LOVE them and want a couple more sets-grandma has these also and bought a second set after a week of using the first set)
3) All sizes of their scrapers (They are good to a high heat, they don't stain - i have left mine in spagetti sauce on accident and withen a couple of washes was back to white-they're up to 4 different sizes now)
Ok there is a 4th, the cooking racks... the choice to stack is great! expecially in my small kitchen. I can fit a 12"x18" cake on one to cool also!
Ok so I really like my pampered chef here are a few other items that I enjoy having.
-Cookie scoops (large one is perfect size for cupcakes/muffins)
-Stoneware (for two people I use the medium bar pan and the large round the most-for family and of the large size ones)
Ok i forgot the items I actually use the most is the Digital Thermometer. It is a timer and attachement for temperatures. This I have had to replace and when I didnt' have one I missed it terribly-it is perfect for all the baking/cooking I do, goes from meats to hard candy. Love it!
Ok I think I probably just doubled your wish list, and made myself want to have another party so i can get more PC stuff.... Hmm wonder how my savings account is looking! LOL
