After a short time bulges in the large pan of soil. Fried eggs flow to the edge of the pan, which roasts not even! Really hot (my oven manufacturer advises not to apply excessive heat pans, Max. Level 7 because I consider myself always) is only the center of the biggest record of my induction hob. There, everything is burning, while the edge is nothing at all. Have the cups now in use for some time and maddens me to have listened to all the great reviews. Absolutely not advise!
