Boil the eggs (7 to 8 minutes to keep them slightly creamy, 9 minutes for fully hard-boiled eggs). Then run them under cold water to stop the cooking and let them cool a little.
3 eggs
Halve the spring onion lengthwise. Slice it into half-rings, rinse in a colander and leave to drain. Alternatively, finely snip the chives.
2 handfuls fresh chives
Leave the capers to drain. Alternatively, chop the pickle and pat it dry.
1 heaped tablespoon capers
Peel the eggs and cut them into pieces.
Place the spring onion, capers and eggs in the bowl. Add all the remaining ingredients, mix, and it's ready.
3 tablespoons mayonnaise, 2 teaspoons Dijon mustard or smooth mustard, 1 tablespoon extra virgin olive oil, 2 teaspoons chili flakes, 3 generous pinches salt (Celtic sea salt), 2 pinches black pepper
