Sweet and Sour Onions
Peel the onions. Bring the vinegar, 250 ml (approximately 8 ounces) of water, the sugar, salt, and spices to a boil. Add the onions, and simmer gently for 3 minutes. Remove the onions from the cooking liquid and layer in clean, sterilized jars.
If you'd like, add a chili pepper to each jar. Bring rhe cooking liquid to a boil, and pour over the onions (making sure the onions are completely covered). Seal the jars immediately, and let the onions infuse for at least 1 week before serving.
