Grand Prize Winner: Island Ahi Burgers With Cilantro-Chile-Lime

The first time I tasted a truly exceptional fish burger, I was on a small, family-run restaurant overlooking the turquoise waters of Maui. The salty air, the gentle sway of the palm trees, and the explosion of flavor in that first bite – it all coalesced into a memory I cherish. The perfectly seared tuna, the bright cilantro, and the subtle heat of the chilies created a symphony of tastes that transported me to paradise. Ever since, I’ve been on a quest to recreate that magic, and this recipe comes remarkably close.

Burgers

• 1 egg
• 1/2 cup panko breadcrumbs (Japanese bread crumbs)
• 4 teaspoons soy sauce
• 4 teaspoons sugar
• 1 tablespoon sesame oil
• 1 tablespoon fresh ginger, minced
• 1 tablespoon garlic, minced
• 2 teaspoons fresh lime juice
• 1 teaspoon lime zest, grated
• 1/2 teaspoon crushed red pepper flakes
• 1/2 teaspoon salt
• 1 1/2 lbs ahi tuna fillets, finely chopped
• 1 tablespoon vegetable oil
• 4 seeded kaiser rolls, split
• 1 large maui onion, thinly sliced (or other sweet onion)
• 1 large vine-ripened tomatoes, sliced
• Radishes (1 package) or sunflower sprouts (1 package)

Equipment Needed

• Gas stove or broiler
• Paper bag
• Small bowl
• Large bowl
• Non-stick griddle
• Toaster or broiler

Instructions

1. Char the Anaheim Chilies: Place the anaheim chilies directly over a gas flame on your stove or under a broiler. Turn them frequently until the skins are blistered and blackened on all sides. This charring process will infuse the chilies with a smoky flavor.
2. Steam the Chilies: Immediately transfer the charred chilies to a paper bag. Close the bag tightly and let them steam for 15 minutes. This will loosen the skins, making them easier to peel.
3. Peel, Seed, and Dice: After steaming, remove the chilies from the bag. Gently peel off the blackened skins. Remove the stems and seeds, then dice the chilies.
4. Prepare the Sauce: Measure 1/4 cup of the diced charred anaheim chilies into a small bowl. Add the mayonnaise, sour cream, cilantro, lime juice, ginger, garlic, and salt. Stir well to combine all ingredients. Set aside.
5. Make the Burger Mixture: In a large bowl, beat the egg. Stir in the panko breadcrumbs, soy sauce, sugar, sesame oil, ginger, garlic, lime juice, lime zest, crushed red pepper flakes, and salt. Mix until well combined.
6. Combine Tuna and Mixture: Gently add the finely chopped ahi tuna to the bowl with the panko mixture. Combine the ingredients delicately, being careful not to overmix. Overmixing can result in tough burgers.
7. Form the Patties: Divide the ahi tuna mixture into 4 equal portions. Gently form each portion into a patty. Be careful not to pack the patties too tightly; they should be relatively loose for a tender texture.
8. Heat the Griddle: Heat the vegetable oil in a non-stick griddle over medium-high heat. Ensure the griddle is hot before adding the patties to achieve a good sear.
9. Cook the Burgers: Carefully place the ahi tuna patties on the preheated griddle. Cook for 3-4 minutes per side, or until the patties are cooked through but still slightly pink in the center. Ahi tuna is best served medium-rare to medium for optimal flavor and texture.
10. Toast the Rolls: During the last few minutes of cooking the burgers, toast the split kaiser rolls under the broiler. Watch them closely to prevent burning.
11. Assemble the Burgers: Spread the prepared cilantro-chili-lime sauce generously on the bottom half of each toasted kaiser roll. Top with sliced maui onion, tomato slices, and either radishes or sunflower sprouts.
12. Add the Patty: Place the cooked ahi tuna patty on top of the toppings.
13. Finish and Serve: Add a dollop of additional sauce on top of the patty, if desired. Place the top half of the kaiser roll on the burger. Serve immediately and enjoy!

Expert Tips & Tricks

• Don’t Overmix: Handle the ahi tuna mixture gently. Overmixing will make the burgers tough.
• Chill for Firmness: For easier handling, chill the formed patties in the refrigerator for 15-20 minutes before cooking.
• Spice Level Adjustment: Adjust the amount of crushed red pepper flakes to your preference. If you prefer a milder flavor, reduce or omit the flakes entirely.
• Anaheim Chili Alternative: If you can’t find anaheim chilies, substitute with poblano peppers.
• Freshness Matters: Use the freshest ahi tuna you can find for the best flavor and texture. Ask your fishmonger for sushi-grade tuna.

FAQs (Frequently Asked Questions)

Q: Can I use frozen ahi tuna for this recipe?
A: Yes, you can use frozen ahi tuna, but make sure it is completely thawed before chopping and mixing it with the other ingredients. Pat it dry to remove any excess moisture.

Q: How do I prevent the ahi tuna burgers from sticking to the griddle?
A: Use a non-stick griddle and make sure it is well-oiled before adding the patties. Also, avoid moving the patties around too much while they are cooking; let them sear properly on each side.

Q: Can I make the cilantro-chili-lime sauce ahead of time?
A: Absolutely! The sauce can be made up to 3 days in advance and stored in an airtight container in the refrigerator. This allows the flavors to meld together even more.

Q: What if I don’t have panko breadcrumbs?
A: You can substitute with regular breadcrumbs, but the texture will be slightly different. Panko breadcrumbs are lighter and crispier, which contributes to a better burger texture.

Q: How do I know when the ahi tuna burgers are done?
A: Ahi tuna is best served medium-rare to medium. Cook the burgers for 3-4 minutes per side, or until they are cooked through but still slightly pink in the center. Avoid overcooking, as this can make the tuna dry.
