FAQs
1. Can I substitute the tilapia with another type of fish?
Yes! Other firm, white fish like cod, snapper, or catfish work well. Cooking time may need slight adjustment depending on the fish's thickness.
2. How can I adjust the spiciness level?
Control the amount of chili peppers you add. Start with less and add more to your taste. You can also use milder chilies or remove the seeds for less heat.
