Red onion pickle

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, /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. Pack the onions into the sterilised jars, sprinkling in a little pepper as you go. Cover with the warm vinegar and finish by tucking a couple of bay leaves down the side of the jars. Seal. The onions are best kept in the fridge and used within to 4 weeks.
