Equipment
- Saucepan
- Wooden spoon (for rotating eggs)
- Timer
- Bowl for soaking onions
- Paper towel
- mixing bowl
- Fork
Ingredients
Core Components
- 2 large eggs 50 g each w/o shell; hard-boiled for exactly 12 minutes
- 1/4 onion Finely minced after soaking
- 1 pickle Finely minced (or 7 cornichons or 4 sweet gherkins)
- 4 Tbsp Japanese Kewpie mayonnaise
- 1 tsp Japanese karashi hot mustard
Seasoning and Brighteners
- 1/4 tsp Diamond Crystal kosher salt
- 1 freshly ground black pepper To taste
- 1/2 lemon Juice only, according to taste
- optional parsley Freshly chopped
Instructions
Egg Preparation (The 12-Minute Boil)
- Submerge the 2 eggs completely in a saucepan of cool water.
- Bring the water to a boil over medium heat while gently rotating the eggs with a wooden spoon to keep the yolks centered.
- Lower the heat to a gentle simmer for exactly 12 minutes once the boil is established.
- Transfer the eggs immediately to a cold water bath to halt the carryover cooking. When cool, peel the eggs.
Onion De-Bitter Soak (Non-Negotiable Step)
- Mince the ¼ onion into tiny, uniform fragments (mijingiri technique).
- Submerge the minced onion in a bowl of ice-cold water and allow it to sit undisturbed for exactly 10 minutes to leach out volatile sulfur compounds.
- Drain the onion thoroughly, place it in the center of a clean paper towel, and squeeze with maximum pressure until the onion feels completely dry to remove excess moisture.
Final Assembly and Emulsion
- Finely mince the 1 pickle.
- In a mixing bowl, mash the peeled 12-minute hard-boiled eggs thoroughly with a fork until partially broken down, creating a secondary emulsion with the yolk.
- Add the dried minced onion, minced pickle, Diamond Crystal kosher salt, freshly ground black pepper, and a squeeze of lemon juice from the ½ lemon.
- Fold in the 4 Tbsp of Japanese Kewpie mayonnaise, the optional parsley, and the 1 tsp of Japanese karashi hot mustard.
- Mix all components together until cohesive. Cover and keep refrigerated until ready to use.
Notes
This sauce is best served with Ebi Fry (deep-fried breaded shrimp) or Tonkatsu. For best flavor integration, allow the sauce to chill for at least four hours before serving; the flavor profile peaks then. If the sauce thickens too much after overnight refrigeration, stir in a few drops of fresh lemon juice to restore silkiness. Store leftovers in an airtight container for up to 3 days.
