This authentic Bundt(r) pan is made of aluminum and bakes best because it conducts heat more evenly than other materials for a perfect finish. Before each use brush with solid vegetable shortening and dust with flour or use baking spray with flour in it which allows the details to be sharper and more defined. Mixes and recipes may vary so fill the pan no more than three quarters full to avoid overflow during baking. You will never have to think "rust" again with this aluminum pan. The nonstick finish is specially formulated to work best with the higher sugar and flour content of cakes and desserts. Before initial use and after subsequent uses, hand-wash with warm, soapy water. Dishwasher use is not rmended, as it may shorten the life of the nonstick coating on your pan. The pan has a 6 cup capacity. Perfect for 6-8 servings.
