For a spicier result, leave whole chilies in the jars during storage.
Cold pickling keeps the onions crisp. Avoid using hot vinegar for pickling if you prefer a crunchy texture.

Quantities of spices can be adjusted based on personal heat preference.
Ensure jars are properly sterilized before use to preserve the pickles safely.
