Baking sheet sets are flat metal pans for oven use, perfect for cookies, biscuits, or roasting. Basics: aluminum for even heat, steel for durability. Beginners need aluminum or aluminized steel—quick heating without hotspots.
Types include: flat cookie sheets (unrimmed, great for flipping cookies), half-sheets (rimmed, versatile for everything), jelly roll pans (smaller, cookie-focused). Start with a half-sheet set—rims catch drips, size suits cookie batches.
Beginner-friendly means simple: no assembly, intuitive sizing, forgiving of overcrowding. Expect even golden cookies on first try, not gourmet perfection.
Marketing traps: 'Non-stick forever' (nothing is); 'commercial' (too heavy). Evaluate by reviews mentioning 'no warping after months' and easy wash.
Realistic: Your first set bakes 1-2 dozen cookies perfectly; upgrade when doing sheet cakes.
