1. Place the frozen product straight into the oven without defrosting it.
2. Bake, in preheated oven, at 180°C for approximately 25 minutes.
3. After it has baked for 15 minutes flip the product over so that the bottom side faces up to ensure even baking and then let it bake for another 10 minutes until it absorbs its oil.
4. Adjust the temperature and the duration of the baking according to your oven.
