Hi, I went to lakeland today as have found a great low carb lamb stew that I wanted to batch cook in a casserole dish. So I bought the hairy bikets marbe effect casserole dish for £25. link here I've just gone to use it and it has a steam vent in it;s lid. I checked online and this means it can only be used on a hob. It didnt say this at all on the box. This may sound very ignorant but I thought casserole dishes were for ovens? I now face a 25 mile trip back to get a refund as the dish is huge and way to big for any of my hob rings.
