Hi, I cook an old family recipe for flapjack. When I was a young girl we had a gas cooker,, my flapjacks were perfect. When I moved out I got an electric cooker my flapjacks just crumbled into a right mess. I then got a gas oven again and wow my flapjacks were perfect again. I now have an electric cooker and once again they are just crumbs. Why will they not cook properly in my electric oven. I thought it might be the moisture that is in a gas oven so I used some water in the bottom but it made no difference. Can anyone help?
