The method
- Place the kipper fillets into a pan (or heatproof bowl) and pour boiling water over them. Leave for 10 minutes until the flesh comes off the bones fairly easily. Carefully remove the small bones.
- Make the hollandaise sauce by melting the butter in a small pan. Put the yolks in a heatproof bowl over a pan of simmering water, slowily beating in the butter with a whisk. Season with lemon juice and salt and then remove from the heat. Whisk the sauce regularly to stop it from separating.
- Halve and toast the muffins. Poach the eggs in a pan of simmering water. For the spinach; wilt gently until cooked, season to taste.
- Top the muffins with the spinach, hollandaise sauce, flaked kipper and poached eggs.
