Salmon, potato, broccolini and Meyer lemon butter

This is one of those dinners that delighted me to prepare, and to see my kids eating with relish. Or gusto, more accurately, as no relish was served. Crispy skinned salmon fillet with a crushed potato (par boiled then smashed and crisped in the pan with salmon), finely sliced broccolini and, the best bit the lemon butter. So that's the juice of one lemon, 20g butter and a shiny, free range egg yolk, whisked over low heat until thickened. Seriously, delicious dinner.
