I am addicted to these, love them in salads, with smoked salmon, fresh salmon, lentils, cured meats... I even like them with burgers. And could not be simpler to make. You need:
- a red onion (sliced very thinly)
- a bay leaf
- 10 black peppercorns
- half a teaspoon of salt
- 100 ml vinegar
- 200 ml water
Heat the water, vinegar, salt, bay leaf and peppercorns in a pan. Put the onions in a jar. When the liquid starts to boil, pour it over the onions, close the lid of the jar and wait for at least one hour. They last for a week and a half or so in the fridge.
