Do Not Throw Out Half-Broken Pretzels, Cake Scraps or Other Leftovers
As a young teenager, Tosi ransacked her mother's cupboards for ingredients, dodging rancid nuts but striking gold with Ritz cracker crumbs and near-empty bags of potato chips containing just the salty dregs. She'd incorporate the leftovers into her baked creations, putting new spins on old favorites and giving them character the standard versions never had. Try it for yourself: Broken Fritos could be the ingredient that elevates your snickerdoodles from very good to "omigod-wow."
Do Not Sift Flour
It's a messy waste of time, Tosi says. Sifting, which aerates the flour and, in turn, the dough, is especially unnecessary with cookies—particularly if they're meant to be rich and dense. You may notice a difference between sifted and unsifted flour if you're making a delicate angel food cake or soufflé. But for buttery, moist cakes, Tosi believes in skipping this process—unless you just can't pass up the opportunity to use your grandmother's antique sifter.
You Don't Need Sharp Knives to Chop Nuts
Most pastry chefs, Tosi included, are not obsessive about sharpening their knives for the simple reason that cutting butter into chunks requires nothing more than a dull-edged cheese spreader. For other jobs, like chopping nuts and candies like peppermints, use a zip-top plastic bag and a meat pounder, a heavy saucepan or the end of a rolling pin.
