I have moved to a house that has a gas oven. I am new to gas ovens. What dishes can we cook in a gas oven? Cake? Are cookies possible to bake in a gas oven?
There are two answers to this question, both are right and they disagree with each other.
Some ovens are better for certain things, electric ovens are good for pastries, gas is better for roasts.
An oven is an oven. A skilled cook can cook a pineapple upside down cake or high tea over a campfire, wood fired pizza oven, or commercial stove with equal panache!
There are differences between types of ovens, and some ovens are superior for certain tasks, but any functional oven can be used to bake almost anything. (Some wood fired bread and pizza ovens are very difficult to cook large roasts in.)
