Who is this Microwave Oven for?

A microwave oven is ideal for evenly and quickly heating food. This can either reheat, defrost, warm, or cook ingredients.

You can bake food and develop crisp textures of vegetables, baked meats, pies, cakes, and delicious caramelized flavours.

The pre-programmed junior menu for pickers and younger eaters is done by just entering the food weight and allowing the combination microwave to do the rest.

This includes vegetable and fruit purees, fried vegetables, fried noodles and more.

Likewise, it is used for complete roasting and baking food that would be overcooked outside or outside the standard microwave.

The hot air circulation in the microwave oven makes it the best choice for cooking food that requires uniform caramelization, crispiness, or browning on the surface.

How To Get The Most Out of It?

It would be best if you considered the power of the convection microwave. Using the oven in convection mode consumes more energy than ordinary microwaves.

If you want a powerful microwave, make sure the power cord has enough capacity and the power supply to operate the appliance.

Most of the models have a power output of about 700 to 1000 watts.

Choose the convection microwave oven that has an inner coated wall. Other than the stainless steel coating wall, it can have acrylic, enamel, or ceramic.

Typically, the enamel-coated model is inexpensive, difficult to clean, and is easy to damage. On the other hand, stainless steel is stronger but easily scratched, and it absorbs odour during cooking.

Likewise, the ceramic model is the best option because it increases its aesthetic value and is easy to clean.

Choose the oven that comfortably fits on the kitchen countertop. If you are planning for the whole kitchen model, you should opt for a built-in microwave to give the kitchen a sleek appearance.

Also, go for the convection microwave oven with the power dial or a timer to approximate the cooking time.

However, some are more advanced with automatic programmes for specific foods.



Can you put metal in the Sharp R82STMA Oven?

No. The metal does not allow microwaves’ penetration, and the food behind the metal won’t cook. Also, metal can cause arcing in the combination microwave.

Does this oven needs to be Ventilated?

No, this is because it uses a fan to circulate air through the oven to assist in cooking more evenly and faster. As long as the new microwave is set up within the space recommended by a manufacturer, no additional ventilation is required.


Alternative Models
