this is a silicone angel food pan. it DOES NOT work for angel food cake, but it DOES for pineapple upside-down cake.
we argued over the flattering individual pineapple cake pans, called for on ROSE’S heavenly CAKES: Individual Pineapple Upside-Down Cakes (page 339). until that pan arrives to my EXTENSIVE collection of cake pans, here is how to make a 9″ full size round cake wreath! use a silicone angel food silicone pan: it is the only tube pan i know of with a perfectly flat bottom.
arrange pineapples and cherries exactly as this picture. this was also argued!
hector’s take resembles a wreath of daisy flowers.
