Some foods such as fish, commercially frozen mince and thin steaks can be safely fried from frozen, using the instructions on the packaging for guidance. Make sure to check the food is fully cooked all the way through before eating, an easy way of doing this is using a meat thermometer.
What is commercially frozen food? Products that are commercially frozen are products and ingredients that have been frozen by the manufacturer before purchase, ensuring it is of the highest quality and can be cooked safely from frozen. This is not the same as home-frozen food.
