Onions in oil

Preparation:

Preparation: Wash the onions, place them in a pan with half a liter of vinegar, a glass of dry white wine, a bay leaf, four cloves, a spoonful of sugar and a pinch of salt. Bring everything to a boil and cook for 10 minutes. After this time, drain the onions, spread them on a clean cloth and let them dry. Finally distribute the vegetables in a series of jars, cover them entirely with olive oil and close the containers. Check the oil level in the following two days, adding more to replace the one absorbed by the onions, then put the jars in a dark and dry place, where the onions will keep for about a year.
