AEG BPK556320M 24 Inch Multifunction PlusSteam Steam Oven. In addition to all your standard oven functions, the PlusSteam button in this SteamBake oven adds steam at the beginning of the baking process. The steam cooking keeps the dough moist on the surface to create a golden color and tasty crust, while the heart stays soft and tender. In addition to baking crispy and tasty breads, muffins and pies – your roasted chicken, grilled spare ribs and lasagna will get equally deliscious and even cooking results.
