This one is an extension of point 3.
Do you want to grill vegetables/meat in your oven?
If yes, then go for ovens which have the Rotisserie function available with them.
With this function, you will get even grilling of meat and veggies. There is provision for grilling in smaller ovens without this function. I tried to make Vegetable Kebabs once in my smaller oven which did not have the rotisserie add-on and the result was not as good as with the rotisserie.
So to sum it up, here are the five questions you should ask yourselves before you choose an Oven for baking cakes, cookies, kebabs at home:
For how many people are you going to bake and how often are you going to use your oven?
What is your budget?
Are you going to need Simple or Advanced levels of baking?
Do you want a dedicated timer when baking for more than 1 hour?
Do you want to grill vegetables/meat in your oven?
So if you are just starting out to bake cakes, have a small family of 3-4 people, then this would be a perfect addition to your kitchen.
Answering these questions will help you choose an Oven Toaster Grill for baking cakes, cookies, kebabs and much more.
To summarize it,
you can get an inbuilt oven or a counter-top oven depending on your space in the kitchen.
If you bake only for friends and family, a counter-top oven should suffice well.
If you plan to start your own baking business in the future, make the investment and go for an inbuilt oven.
