In the preparation of a Kamikaze shot, what ingredient is mixed with vodka and triple sec?

In a Kamikaze shot, lime juice is the key ingredient combined with vodka and triple sec. This mixture creates a balanced flavor profile that is both tart and citrusy, which complements the sweetness of the triple sec and the neutral base of vodka. The fresh acidity from the lime juice enhances the overall taste, making it a popular choice for those looking for a shot that is refreshing and easy to drink.

Other ingredients, like peach schnapps, cranberry juice, and orange juice, are typically used in different cocktails but do not contribute to the classic composition of a Kamikaze. Each of those options would alter the intended flavor profile of the shot, moving it away from the traditional combination that features lime juice.
