Tips for cooking
Please make sure to preheat the oven before baking. If the oven does not have a preheating function, set the temperature and heat for 10 minutes before baking. The strength of the heat may vary depending on the type of oven and the period of use. Please make sure to follow the recipe as a guide but adjust the baking time as needed. If it browns too fast, cover it with aluminum foil.
