Add the listed amount, or as many sliced shallots as you'd like, to a jar and pour in the lime juice. Use enough to cover them by at least ¼ inch.
Let the shallots marinate for at least 30 minutes, and up to a week.
Notes
These can be "quick pickled" in 30 minutes -- however, the longer they marinate in the lime juice, the more intense the flavor will be.Calorie count is only an estimate.
