2. When baking ham in the oven, put the ham in the microwave oven, adjust the oven to 180-200 degrees, and bake for about 10 minute. It should not be too long to bake ham in the oven, so as not to zoom the appearance of ham and affect the taste and beauty. Ham can be eaten directly after baking, or it can be eaten with cumin powder, tomato sauce and other ingredients.
