What additional ingredient is topped on a Tall Chestnut Praline Latte?

The reason "whip and praline topping" is the correct answer lies in the Starbucks Chestnut Praline Latte's signature presentation and flavor profile. This drink is designed to combine the creaminess of steamed milk with espresso and the sweet, nutty flavors of chestnut. Topping it with whipped cream adds a rich, velvety texture that enhances the overall experience, while the praline topping introduces a delightful crunch and a hint of sweetness that complements the latte’s flavors. This specific combination not only makes the beverage visually appealing but also elevates the taste, making it a popular choice during the holiday season when it is typically offered.

In contrast, options like caramel drizzle, crushed walnuts, or chocolate shavings do not typically accompany this particular drink, either because they belong to other menu items or do not align with the flavor profile intended for the Chestnut Praline Latte.
