Follow the master commands
Peel the onions, cut them in half from top to bottom and finely slice into half-moon pieces. Put in a colander placed over a bowl and sprinkle with salt, lightly turning over the onion pieces with your hands so the surfaces are all covered. Set aside for an hour or so to brine.
Meanwhile put the vinegar, 50ml/2fl oz water and the sugar in a saucepan. Bring to a simmer, stirring to help the sugar dissolve, and cook for a couple of minutes. Set aside.
