No,not cream eggs, Balti pans (Karahi). I believe the dishes should be so hot that the curry sizzles when you put it in. I have put them in the oven for about 10Min's they seem hot but no sizzle. I have heated them on the gas ring and they ping and boing and the bottom goes black. I have boiled water in them to heat them up,but the minute I empty it out they have gone cold. They were ?2 each from ASDA so maybe you get what you pay for.. any ideas...
