Copenhagen does not have to use cod, it can be replaced

The recipe improvements are as follows:

1. Boiled eggs---priority suggestion Steamed eggs and stewed eggs are not fried, and can be paired with vegetables to make egg soup.

2. Cod---it is recommended to replace the fish with tuna.

3. Ham slices---it is recommended to replace it with an equal amount of chicken breast.

4. Orange juice---it is recommended to choose 200ml with NFC logo, or weigh 400g orange/tangerine/grapefruit with the skin and eat it directly.

5. White cheese---There is no substitute. It is recommended to make homemade cheese with 500ml skim milk + 1 lemon. The app has a tutorial.

6. Beef and mutton can be replaced with each other.

7. Carrots---It is recommended that the raw weight be 200g, and replace it with ordinary pumpkins other than Beibei and chestnut pumpkins.
