What is the reason why the things baked in the oven died?

1. The reason why things baked in the oven are bitter is that the cooking oil in the oven may be bitter after repeated use, and then there is the quality problem of the ingredients themselves. Add some substances to cover up the spoiled meat, and it may be bitter when roasting.

2. There is also the wrong time to sprinkle ingredients during the barbecue, or it may be that some ingredients are sprinkled. If sprinkled too early and baked for too long, it will be very bitter. They should be burnt, and the nutritional structure of food has been completely destroyed! So it's bitter. Eating too much will cause cancer.
