Quick Answers
Do I need a claypot?
No, a heavy-bottomed pan works just as well. It distributes heat evenly for a perfect braise. A Dutch oven is also a great choice.
What fish is best?
Catfish is traditional and holds up beautifully. Tilapia or salmon are excellent alternatives. Choose a firm white fish for the best results.
Is it too spicy?
The heat is adjustable by removing the chili seeds. You can also omit them entirely. The caramel sauce provides plenty of flavor alone.
I hope this warm and savory dish brightens your winter evening. It is the perfect way to bring new flavors to your table. Happy cooking!
