Method

• 1.
  Bring a saucepan of water to the boil over high heat. Gently add whole eggs, reduce heat to medium and simmer for 8 minutes.
• 2.
  Remove from pan and place in iced water for 10 minutes, then peel and set aside.
• 3.
  To make the mayonnaise, place yolks, vinegars, lemon juice and mustard in a bowl and whisk to combine. Slowly pour in the oil in a thin, steady stream, whisking constantly, until thick. Season with salt and pepper. (Mayonnaise can be stored in a container in the fridge for up to 3 days.)
• 4.
  Slice eggs in half lengthways and place, cut-side down, on a plate. Spoon 1 tbs mayonnaise over each half, sprinkle with chives and chervil. Top with caviar to serve.
