Ingredients You’ll Need for Sea Urchin Sauce

To create the perfect sea urchin sauce, it’s important to use fresh, high-quality ingredients. Here’s what you’ll need:

1. Fresh Sea Urchin (Uni)

The star of the sauce is, of course, the sea urchin. Fresh uni has a creamy texture and a sweet, briny flavor that forms the base of the sauce. You’ll want to use the best quality sea urchin you can find to ensure a rich, flavorful sauce.

Where to Buy: High-quality fresh sea urchin can be found at Global Seafoods , where you can purchase uni sourced from sustainable fisheries.
Amount: 2 to 3 ounces of fresh sea urchin roe (about 6 to 8 pieces of uni).

2. Cream or Mayonnaise

To give the sauce its creamy consistency, you’ll need to add a small amount of cream or mayonnaise. Cream will give the sauce a silky texture, while mayonnaise adds a slightly richer, tangy flavor. Choose your preference based on the flavor profile you’re aiming for.

Cream: Heavy cream for a smooth, mild flavor.
Mayonnaise: Japanese mayonnaise (such as Kewpie) for a tangier, richer sauce.

3. Soy Sauce

A touch of soy sauce adds depth and umami to the sauce, balancing the sweetness of the sea urchin. Use light soy sauce for a more delicate flavor, or regular soy sauce for a bolder taste.

Soy Sauce: 1 to 2 teaspoons, to taste.

4. Sake or Mirin

For a traditional Japanese touch, add sake or mirin to the sauce. Sake adds complexity and a subtle alcoholic warmth, while mirin brings a mild sweetness that complements the brininess of the uni.

Sake or Mirin: 1 tablespoon.

5. Citrus (Optional)

For a refreshing brightness, you can add a splash of citrus juice like lemon or yuzu. This helps cut through the richness of the sauce and adds a layer of acidity that pairs well with raw fish.

Citrus Juice: 1 teaspoon of lemon or yuzu juice.

Step-by-Step Instructions to Make Sea Urchin Sauce

Follow these simple steps to create a rich, creamy sea urchin sauce that’s perfect for sushi:

1. Prepare the Sea Urchin

Start by gently scooping the fresh sea urchin roe into a small mixing bowl. Use a non-metallic spoon to avoid altering the delicate flavor of the uni. Mash the uni gently with a fork or spoon until it forms a smooth, creamy paste.

Tip: Be gentle to preserve the creamy texture of the sea urchin.
Mashing: The consistency should be thick and smooth.

2. Add Cream or Mayonnaise

Next, add 1 to 2 tablespoons of heavy cream or mayonnaise to the mashed sea urchin. Stir until fully incorporated, creating a silky, smooth sauce. If using mayonnaise, start with 1 tablespoon and add more if you want a richer flavor.

Tip: Adjust the cream or mayo to achieve your desired consistency.

3. Mix in Soy Sauce and Sake/Mirin

Add 1 to 2 teaspoons of soy sauce and 1 tablespoon of sake or mirin to the mixture. Stir well to combine all the flavors. This will add depth and balance to the sauce, enhancing the natural sweetness of the uni.

Tip: Taste the sauce and adjust the amount of soy sauce to suit your preference.

4. Add Citrus (Optional)

If you prefer a brighter, slightly tangy sauce, add 1 teaspoon of lemon or yuzu juice to the mixture. This step is optional but recommended if you’re serving the sauce with lighter fish or sashimi.

Tip: Yuzu is ideal for a more traditional Japanese flavor, while lemon works well for a subtle brightness.

5. Blend Until Smooth

For a smoother, more refined sauce, use a blender or immersion blender to puree the mixture until it’s completely smooth. This will create a velvety texture that’s perfect for drizzling over sushi or sashimi.

Tip: Blending helps achieve a professional, restaurant-quality consistency.

How to Use Sea Urchin Sauce in Sushi Dishes

Now that you’ve made your sea urchin sauce, it’s time to enjoy it! Here are some creative ways to use the sauce to enhance your sushi dishes:

1. Drizzle Over Sushi Rolls

For an elevated sushi experience, drizzle your homemade sea urchin sauce over sushi rolls. It pairs beautifully with rich, fatty fish like tuna or salmon, as well as more delicate seafood like scallops or shrimp. The sauce adds both flavor and a touch of luxury to any sushi roll.

Pair With: Tuna, salmon, scallops, or shrimp rolls.
Serving Tip: A light drizzle is all you need to elevate the flavor of the roll without overpowering it.

2. Serve with Sashimi

Sea urchin sauce is an excellent complement to sashimi, providing a rich, creamy contrast to the clean flavors of raw fish. You can either serve the sauce on the side for dipping or drizzle a small amount directly onto the fish.

Pair With: Salmon, tuna, yellowtail, or scallop sashimi.
Serving Tip: Serve the sauce in a small dish alongside soy sauce and wasabi for a complete sashimi experience.

3. Add to Seafood Bowls

A spoonful of sea urchin sauce can take a simple seafood bowl to the next level. Drizzle the sauce over a poke bowl or chirashi bowl for a rich, creamy addition that complements the fresh fish and vegetables.

Pair With: Seafood bowls with tuna, shrimp, or lobster.
Serving Tip: Add a touch of sesame seeds or sliced avocado for extra flavor and texture.
