Forget the tube or loaf ban when making a pound cake and try the age-old custom of baking the cake in a cast-iron pan. I have a collection of pans in all sizes and use them nearly exclusively for everything. For cake baking (or pastry) the method offers a new dimension but one that’s so old fashioned you wonder why you haven’t used this method regularly. The big difference is in the finished texture and taste of the cake.
It develops a wonderful top crust and the interior of the cake is richer and fuller; somehow all the ingredients of butter, sugar, flour, heavy cream and vanilla coalesce into what I think is the ultimate pound cake: big texture and flavor from baking it in such a heavy-guage pan that conducdts the heat so well.
