start by peeling your onions and then slicing them, trying to keep the slices intact

heat a cast iron pan and fry the onion slices without oil until they get charred spots

meanwhile, mix the water, vinegar, and sugar in a pot and simmer it until the sugar dissolves

now, start stacking the onions in your preserving jars, add the optional spices, and fill the jars to the top with the hot liquid

screw the jars tightly and let them cool

you can use the onions the next day and they will keep in the fridge for around 2 weeks.
