Circulon Ultimum Mini Oven Tray 5 "Nothing sticks!" Ms Crowe 13 March 2019 I've been so impressed I've replaced most of my bakeware with Circulon Ultimum. Nothing sticks. Not even sticky ribs in a sugary BBQ sauce. I'd normally be soaking and chiselling to get the tray clean - just wiped off! Can I give 6 stars?
