I'm used to using an electric oven, and have just bought a new gas oven.
I've found that it doesn't seem to brown food very well, and in some instances over cooks food from underneath.
For example, today I put in some veggie sausage rolls. In my electric oven, they used to brown on the top and that's how I could tell they were cooked. In my gas oven, the top looked completely uncooked whilst underneath got a bit burnt.
Am using the recommended oven settings.
