Break the eggs into a bowl, add some salt and pepper and lightly break up with a fork – but don’t whisk them, I like the finished egg to be a bit lumpy.
Melt the butter in a pan, add the eggs, leave for a few seconds then stir with a wooden spoon until you have reached the degree of firmness that you like – I like them to just hold their shape.
Remove from the heat and stir in the cream.
Spoon the eggs alongside the smoked salmon, with a little pile of thinly sliced onion and some capers.
