Essential Ingredients

Every ingredient in this salad plays a unique role in achieving its signature flavor and texture.

Sweet Potatoes (350–400 g)

Japanese sweet potatoes are known for their deep yellow flesh and rich, sweet flavor. They hold their shape well when cooked and provide a naturally creamy texture.
Substitution: You can use orange sweet potatoes or yams if Japanese varieties aren’t available, but the flavor will be slightly earthier.

Mayonnaise (3 tablespoons)

Japanese mayonnaise (like Kewpie) is creamier and slightly tangier than regular mayonnaise, giving the dressing a smooth finish.
Substitution: You can use any high-quality mayo, or try Greek yogurt for a lighter version.

Whole-Grain Mustard (2 tablespoons)

Mustard adds a touch of sharpness and texture to the dressing. The little mustard seeds pop pleasantly when you eat the salad.
Alternative: Dijon mustard or spicy mustard works fine too, though the flavor will be more intense.

Honey (1 tablespoon)

Honey brings a gentle sweetness that balances the saltiness of soy sauce and the tang of mustard.
Variation: Maple syrup or agave nectar can be used if you prefer vegan options.

Soy Sauce (1 teaspoon)

A small splash of soy sauce deepens the flavor, giving it a savory umami base.
Substitution: Tamari or coconut aminos are good alternatives.

Salt (a pinch)

Even though soy sauce adds saltiness, a small pinch enhances all other flavors.

Step-by-Step Instructions

Follow these simple steps to create the perfect Sweet Potato and Honey Trout Salad at home.

Step 1: Prepare the Sweet Potatoes

Peel and dice the sweet potatoes into small, even cubes (about 2 cm each). Soak them in water for 10 minutes until the water runs clear—this helps remove excess starch and keeps the pieces from becoming sticky when cooked. Drain well.

Place the sweet potato cubes in a heat-resistant bowl, cover loosely with plastic wrap, and microwave at 600 W for 4 – 4.5 minutes until soft but not mushy. You can also steam or boil them if you prefer, but microwaving saves time.

Step 2: Lightly Mash

While the sweet potatoes are still warm, mash them halfway with a masher or fork. You should leave some chunks for texture. Allow them to cool slightly before adding other ingredients—this prevents the dressing from becoming too thin.

Step 3: Make the Dressing

In a small bowl, mix the A ingredients:

• 3 tablespoons mayonnaise
• 2 tablespoons whole-grain mustard
• 1 tablespoon honey
• A pinch of salt
• 1 teaspoon soy sauce

Stir until the mixture becomes creamy and well blended.

Step 4: Combine Everything

Pour the dressing over the cooled sweet potatoes. Gently mix until each piece is coated evenly. Be careful not to over-stir—keeping some chunks intact adds a pleasant bite.

Step 5: Add the Trout

For the “honey trout” element, use lightly smoked or pan-seared trout fillets. Break them into bite-sized pieces and gently fold them into the salad. The mild saltiness of trout pairs perfectly with the sweet dressing.
If you can’t find trout, salmon or mackerel are great substitutes.

Secrets to Success and Expert Tips

1. Use Japanese sweet potatoes if possible. Their natural sweetness and creamy texture make this salad uniquely delicious.
2. Let the potatoes cool slightly before mixing the dressing to keep it creamy instead of watery.
3. Don’t overmash. A mix of smooth and chunky textures creates the best mouthfeel.
4. Add fish last. Fold it gently so the delicate flakes don’t break apart.
5. Taste and balance. Adjust honey and mustard amounts depending on how sweet or tangy you like it.

Expert Tip: Roast your sweet potatoes instead of microwaving for a deeper caramel flavor. Drizzle a bit of olive oil before baking at 200 °C for about 20 minutes. It adds a nutty aroma and beautiful golden color.

Assembly

Now comes the fun part—assembling and presenting your Sweet Potato and Honey Trout Salad.

1. Spoon the mixture onto a shallow plate or wide Japanese bowl.
2. Add extra trout pieces on top for presentation.
3. Drizzle a small amount of honey mustard dressing on top for shine.
4. Sprinkle freshly ground black pepper or sesame seeds for contrast.
5. Garnish with microgreens or thinly sliced scallions for color.

Presentation Tips

• Use a white Japanese plate to highlight the salad’s natural colors.
• Serve slightly warm for comfort or chilled for a refreshing summer option.
• Add side items like steamed broccoli, cherry tomatoes, or boiled eggs for a complete meal.

Storage and Make-Ahead Tips

This salad keeps surprisingly well if stored correctly.

• Refrigeration: Place leftovers in an airtight container and refrigerate for up to 2 days.
• Do not freeze—the mayonnaise dressing may separate and change texture.
• Make-ahead: You can cook and mash the sweet potatoes a day earlier. Store them separately and add the dressing and trout just before serving for the best flavor.

Reheating: If you prefer it warm, gently microwave the sweet potato portion (without the fish) for 30 seconds, then add the trout before serving.

Recipe Variations

One of the best parts of this recipe is how versatile it is. You can easily adapt it based on your mood or the ingredients you have at home.

1. Vegetarian Sweet Potato Salad
Skip the trout and add roasted nuts (like walnuts or almonds) for crunch. You can also mix in cooked edamame or tofu cubes for protein.
2. Spicy Honey Mustard Version
Add a small amount of chili flakes or wasabi to the dressing for a spicy Japanese kick.
3. Citrus Twist
Add a teaspoon of lemon or yuzu juice to the dressing for a refreshing tang. This version pairs beautifully with grilled fish or chicken.
