Can I use a different fish instead of mahi-mahi?
Yes. Cod, halibut, or snapper work well as firm-fleshed alternatives that hold up on the griddle.
How do I know when the fish is done on the griddle?
The fish should flake easily with a fork and reach an internal temperature of 145°F (63°C). Avoid flipping too early; cook until the bottom releases easily, typically 3-4 minutes per side.
Can I make the salsa and crema ahead of time?
Yes. Both can be prepared up to 4 hours ahead. Store separately in airtight containers in the refrigerator to prevent the avocado crema from browning.
What if I don't have fresh mango?
Frozen mango (thawed and drained) works well, though fresh offers better texture. Avoid canned mango in heavy syrup, as it will make the salsa watery.
How spicy will these tacos be?
One diced jalapeño in the salsa and one in the crema provides mild-to-medium heat. Remove seeds for less spice, or add more jalapeños for extra kick.
