Creamy Japanese Potato Salad Ingredients

For the Salad
Potatoes This key ingredient provides the structure and creaminess; prefer waxy or Yukon gold for the best texture.
Cucumber Adds a refreshing crunch; a small cucumber is ideal to keep excess water at bay.
Carrot Offers a pop of color and sweetness; you can choose to grate or slice it into strips.
Hard Boiled Eggs Adds richness and protein; use about 2 eggs, chopped roughly.
Japanese Kewpie Mayonnaise This gives the salad its creamy texture and unique umami flavor; substitute regular mayonnaise if needed, though taste will vary.
White Vinegar Balances the mayonnaise with tanginess; rice vinegar can replace it for a milder note.
Hot Mustard Enhances flavor with a slight kick; adjust to taste or omit for a milder version.
Spring Onion (Scallions) Provides fresh, crisp notes; use finely sliced green parts for both color and flavor.
Japanese Furikake An optional seasoning that boosts umami; look for it in Asian grocery stores.
Sea Salt Crucial for seasoning throughout the preparation; don t forget to sprinkle as you mix.

How to Make Creamy Japanese Potato Salad

1. Boil Potatoes: Place the peeled and cubed Yukon gold potatoes in a pot of salted water. Boil for about 25 minutes until fork-tender, then drain and set aside to cool slightly.
2. Prepare Vegetables: While the potatoes are cooking, sprinkle the finely chopped cucumber and grated carrot with a pinch of salt. Let them sit for about 10 minutes to draw out excess moisture, then gently squeeze out any liquid.
3. Chop Potatoes: Once the potatoes are cool enough to handle, peel off the skins and cut them into rough chunks. Aim for a mix of sizes for great texture.
4. Mix Ingredients: In a large mixing bowl, combine the warm potato chunks with the salted cucumber, carrot, roughly chopped hard-boiled eggs, Kewpie mayonnaise, white vinegar, hot mustard, and sliced spring onions.
5. Combine Gently: Carefully fold all the ingredients together until just combined, ensuring some potato chunks remain intact for a lovely texture.
6. Season and Serve: Taste your salad and season with additional sea salt if needed. If desired, sprinkle a dash of Japanese furikake on top for a burst of flavor before serving.

Optional: Serve chilled for a refreshing taste.
