Do you bake? No? Well, do you sometimes reheat leftover pizza or make the biscuits that come packaged in a cardboard tube? Gotcha!
You need to get a SILPAT, a non-stick baking mats made of fiberglass and silicone that can be re-used thousands of times. They're especially great for working with sticky materials such as gooey batters, taffy or caramel, nothing sticks to this thing. It will save you a lot of time cleaning as there are no more sticky baked on messes to scrub off your pans! It never needs greasing, which saves both time, money and maybe a calorie or two.
My mom got me my first one over 10 years ago and now I have several on hand as I won't use a cookie sheet without one.
You can get yours at Bed Bath & Beyond. It'll be the best $20 you'll ever spend. Alright, maybe not the best but I promise you won't regret it!
