Ahi Steak With Li Hing Mui Butter: A Taste of Aloha

The first time I tasted li hing mui was at a roadside shave ice stand on Oahu. The tart, salty, slightly sweet powder, sprinkled generously over the icy treat, was an explosion of flavor unlike anything I’d experienced. It instantly transported me to sun-drenched beaches and gentle ocean breezes. Since then, I’ve found myself adding li hing mui to everything from popcorn to pineapple, always chasing that perfect balance of sweet, sour, and salty that defines island cuisine. Now, blending it into a rich, savory butter to top seared ahi? That’s a truly special marriage of flavors.

Recipe Overview

Prep Time: 15 minutes
Cook Time: 8 minutes
Total Time: 23 minutes
Servings: 4
Dietary Type: Pescatarian

Ingredients

1/4 cup vegetable oil
2 tablespoons lemon juice
1 tablespoon lime juice
1 1/2 lbs tombo ahi tuna steaks, sliced 1/2-inch thick
1/4 cup butter, softened
1/2 tablespoon li hing mui powder (plum powder)
1/2 tablespoon ground macadamia nuts
Salt and pepper, to taste

Equipment Needed

Small bowl
Whisk or fork
Shallow dish or resealable bag
Electric grill or broiler
Baking sheet (if using broiler)

Instructions

First, prepare the Li Hing Mui Butter. In a small bowl, combine the softened butter, li hing mui powder, and ground macadamia nuts. Mix thoroughly with a fork or whisk until well combined. Transfer the mixture to a piece of plastic wrap and shape into a log. Wrap tightly and refrigerate until needed. This allows the flavors to meld together and the butter to firm up, making it easier to slice and serve.
Next, prepare the Ahi Tuna Marinade. In a shallow dish or resealable bag, whisk together the vegetable oil, lemon juice, and lime juice. This citrus marinade will lightly “cook” the outside of the tuna and impart a bright, tangy flavor.
Marinate the ahi tuna steaks in the lemon juice mixture for 1 to 2 hours in the refrigerator. This step is crucial for flavor infusion. Be careful not to marinate for too long, as the acid in the citrus can break down the fish and make it mushy.
Preheat an electric grill or broiler to 500°F (260°C). Ensure your grill is clean and lightly oiled to prevent sticking. If using a broiler, place the top rack about 6 inches from the heating element and line a baking sheet with foil.
Remove the ahi tuna steaks from the marinade and discard the marinade. Gently pat the steaks dry with paper towels. This will help them sear properly and develop a beautiful crust.
Grill the ahi tuna steaks for about 7 to 8 minutes total, flipping halfway through. The exact cooking time will depend on the thickness of the steaks and your desired level of doneness. Ahi is best served rare to medium-rare, so be careful not to overcook it. The center should still be slightly pink. To check for doneness, gently press the center of the steak with your finger. It should feel slightly firm but still have some give.
Season the grilled ahi tuna steaks with salt and pepper to taste. Freshly ground black pepper and sea salt flakes will elevate the flavor even further.
Remove the Li Hing Mui Butter from the refrigerator and slice into 1/4-inch thick rounds.
Place a tablespoon of li hing mui butter on top of each ahi tuna steak. If using a broiler, place the steaks under the broiler for a minute or two, or until the butter begins to melt. Watch carefully to prevent burning. If using a grill, simply let the residual heat melt the butter.
Serve immediately and enjoy the explosion of Hawaiian flavors!

Expert Tips & Tricks

Don’t overcook the ahi! Ahi is best served rare to medium-rare. Overcooked ahi will be dry and tough. Use a meat thermometer for precise cooking; aim for an internal temperature of 125-130°F (52-54°C) for medium-rare.
Sear, don’t steam: Make sure your grill or pan is hot enough to create a nice sear on the outside of the ahi. This will give it a great texture and flavor.
For a deeper flavor, lightly toast the macadamia nuts before grinding them. This will bring out their natural oils and enhance their nutty aroma.
Make the Li Hing Mui butter ahead of time: The butter can be made several days in advance and stored in the refrigerator. This will save you time on the day of serving.
If you don’t have li hing mui powder, you can substitute it with umeboshi plum paste, finely chopped. However, the flavor will be slightly different.
For extra flavor, add a clove of minced garlic or a pinch of red pepper flakes to the Li Hing Mui butter.

Serving & Storage Suggestions

Serve the Ahi Steak with Li Hing Mui Butter immediately after cooking. Garnish with fresh cilantro or green onions for added freshness and visual appeal. Consider serving with a side of coconut rice, grilled asparagus, or a fresh mango salsa for a complete Hawaiian-inspired meal.

Leftover Ahi Steak should be stored in an airtight container in the refrigerator. It is best consumed within 1-2 days. Reheat gently in a pan over low heat or in a microwave. Keep in mind that reheating may further cook the ahi, so be careful not to overcook it. The Li Hing Mui Butter can be stored in the refrigerator for up to a week or in the freezer for up to a month.
