[alternatively, you could use 2 teaspoons of pickling spice in place of the whole spices]
1 large red onion, thinly sliced
Instructions
In a small saucepan, bring the vinegar, sugar, salt and spice to a boil; stir until the sugar and salt have dissolved. Add the onion slices and return to a boil. Reduce heat and simmer for 20 minutes, stirring and submerging the onions. Remove from heat and let cool in the pan. Once cooled to room temperature, transfer to an air-tight storage container and store in the fridge for up to 1 week.
