Cooling Rack Duo 5 "Such a COOL duo!" Mrs Audrey Mitchell 07 January 2019 I was very pleased with my new cooling rack duo. The best I've ever had as they are so sturdy and robust and easy to clean. The two different sizes can accommodate most sizes of cakes/bread etc. and can, of course hold plenty of buns and muffins or whatever you may choose to bake! I would recommend them most highly.
