Ingredients

• 2 pieces Fresh mackerel fillet
• 1 medium head Cauliflower
• 2 tablespoons Cream cheese
• 1 tablespoon Rice vinegar
• 1 tablespoon Soy sauce (optional for serving)
• 0.5 teaspoon Salt
• 1 sheet Nori sheets
• 1 teaspoon Wasabi (optional for serving)
• 1 tablespoon Pickled ginger (optional for serving)

Directions

Step 1

Begin by preparing the cauliflower rice. Remove the leaves and the core from the cauliflower and cut it into chunks.

Step 2

Place the cauliflower chunks in a food processor and pulse until the texture resembles rice grains.

Step 3

Transfer the cauliflower rice to a microwave-safe bowl and microwave on high for 3-4 minutes until it's tender, stirring halfway through.

Step 4

Once cooked, allow the cauliflower rice to cool slightly and then squeeze out any excess moisture using a clean kitchen towel.

Step 5

In a large bowl, combine the cauliflower rice, cream cheese, rice vinegar, and salt. Mix well until the mixture holds together like sticky rice. Adjust seasoning as needed.

Step 6

Cut the fresh mackerel fillet into thin slices, approximately 1/4 inch thick, ensuring each piece is large enough to cover a small oval of rice.

Step 7

Using wet hands, form small oval-shaped mounds of the cauliflower rice mixture, roughly 1 tablespoon each.

Step 8

Place a slice of mackerel over each rice mound, pressing gently so it adheres.

Step 9

Using kitchen scissors, cut the nori sheet into thin strips. Wrap a strip around the center of each nigiri to secure the fish to the rice.

Step 10

Arrange the mackerel nigiri on a serving platter.

Step 11

Serve with soy sauce, wasabi, and pickled ginger on the side, if desired.
