Help me please! I've recently moved to a house with a gas oven and it is my first time using one. Cooking oven dishes is okay, but baking has been a disaster!! Following recipe gas marks and timings, I have attempted a chocolate cake and some bread rolls, both simple stuff that I would make perfectly in an electric oven. Both came out with burnt bottoms and uncooked tops in this oven! So what's the deal, what am I missing? Please help!!
