Keeps Your Food Fresh and Warm
When we have a big dinner, it sometimes requires going to the oven often and when batches are involved, the earlier ones can get cold before the cooking is done. Aluminum foil can help make this easier because of its heat-conserving property.
It is important to note that the foil doesn’t make the food warm, instead it can help keep the food warm for a longer time by conserving heat or trapping the hot air inside. It serves as an insulator and prevents the exchange of the hot air inside with the cool one outside. To achieve this, wrap each batch with the foil while it’s still hot.
