Method
Hard-cook the eggs
- Place 6 eggs in a 3-quart saucepan.
- Add 2 quarts cold water to cover them by 1 inch.
- Bring the water to a full boil over high heat.
- Cover the pan.
- Remove the pan from the heat.
- Let the eggs stand for 12 minutes.
- Transfer the eggs to cold water, adding more water for cooling, and cool completely.
- Peel the eggs.
- Halve the eggs lengthwise.
- Place the whites cut-side up on a tray.
- Put the yolks in a medium bowl.
Make the filling
- Mash the yolks with the mayonnaise, Dijon mustard, vinegar, salt, and pepper until smooth.
- Cover and refrigerate the filling while you bread and fry the whites.
Bread and fry the whites
- Pat the egg whites dry.
- Set out three shallow bowls with the flour, the 2 remaining eggs beaten until blended, and the panko.
- Pour the vegetable oil into a 12-inch high-sided skillet.
- Heat the oil over medium heat to 350°F, checking with a thermometer.
- Coat the whites in flour, then beaten egg, then panko, pressing the crumbs on gently.
- Shallow-fry in batches for 2 to 3 minutes, turning gently once, until crisp and golden; keep the oil near 350°F.
- Transfer the fried whites to a paper-towel-lined plate.
- Let the fried whites cool for 5 minutes.
- Spoon or pipe the chilled filling into the centers.
- Serve.
Notes
Keep the oil near 350°F so the coating crisps without becoming greasy. Refrigerate leftovers in an airtight container for up to 2 days; freezing is not recommended. For a gluten-free option, use gluten-free flour and panko.
