Circulon Ultimum 20cm Sandwich Cake Tin 5 "Best thing ever!!" Lynne 13 June 2019 Okay I was at least to say sceptical about this saying that it was guaranteed non stick. so thought I would not even put any liner or spray on it to try it out. I had to make a Victoria Sponge. They came out of the oven and thought I will leave them for 10 mins. Needs to be left a little longer and came out perfectly. Now I am convinced but now this is going to cost me money as I want to replace all my bakeware with Circulon Ulitimum ware, I don't think my husband will be very pleased, Oh well....
