Common Questions
Do I need a traditional clay pot?
No, a heavy-bottomed stainless steel or cast iron pan works perfectly. The key is even heat distribution for the caramel.
Is this dish very spicy?
The chilies provide a gentle heat that balances the sugar. You can remove the seeds to keep it very mild.
I hope this savory Vietnamese Caramelized Fish brings warmth to your winter table. It is a simple joy to cook and even better to share.
