This is extremely dangerous and can lead to a fire hazard or damage the toaster.
Toasters are designed to toast slices of bread and are not intended for other types of food or materials. When you put inappropriate items like cooking dough or aluminum foil into a toaster, you risk causing a short circuit, electrical fires, or damaging the heating elements. Additionally, if the toaster malfunctions, it could lead to a risk of electric shock or other injuries.
If you want to cook or heat items like dough or other food, it's important to use the appropriate kitchen appliances designed for that purpose, such as an oven or microwave. Always follow the manufacturer's instructions and safety guidelines when using any electrical appliance to avoid accidents and ensure your safety.
Remember, using appliances in unintended ways can have serious consequences, so it's best to stick to their intended use and avoid any potential risks.
