Sometimes it pays to be cheap.
Expensive baking sheets are easily the greatest scam perpetrated on the general baking public. Simple, aluminum sheet trays are the most versatile option available. A standard half-sheet tray (18”x13”) is perfect for most home ovens and can be found for as little as $3.49 at online restaurant supply stores. Pair it with that new baking mat, and you’re good to go for cookies, cakes, and all of your savory cooking projects as well.
Plastic wrap is another essential that I will only buy in large quantities. Anyone who has fumbled in frustration with brand-name plastic wrap, which always seems too narrow for the job at hand or too determined to stick to nothing but itself, will love the 2-foot width of a commercial roll. And if you have space for 2,000 feet, you’ll be triple-wrapping everything in your kitchen for years to come for less than $18. The equivalent amount of inferior brand-name wrap will set you back at least $100. Easy math.
The last item I buy in restaurant volumes is parchment paper. Like plastic wrap, retail prices are painful. William Sonoma silicone-coated baking papers cost $49.95 for 250. In bulk, the price is $51.99 for 1,000.
Get an 18"x13" sheet tray for $3.49, a 2,000-foot package of plastic wrap for $17.49, and a 1,000-sheet case of parchment paper for $51.99, all from from Webstaurant Store.
