Oysters Not Opening
Your oysters stayed closed because they were dead or lacked enough steam. Steam longer and discard any that stay shut.

The fix
Tap a step to check it off.
- 1 add 2 tablespoons water or wine, cover, and steam 2 to 3 minutes more
- 2 shake the pot once to redistribute heat
- 3 discard any oysters that remain closed after cooking
If it's still wrong
- Use only the opened oysters and discard the rest.
- Steam in smaller batches for more even heat.
Prevent next time
- Check that shells close when tapped before cooking.
- Keep oysters cold and cook the same day.
Notes
Why this works
Steam penetrates the shells and relaxes the adductor muscle. Closed oysters after cooking are usually dead and should be discarded for safety.
