Which of the following is NOT an ingredient in vanilla syrup?

Vanilla syrup is typically made using a combination of water, sugar, and vanilla extract. These ingredients work together to create a sweet and flavorful syrup that is often used in beverages, desserts, and other culinary applications.

Water serves as the base of the syrup, providing the necessary liquid component to dissolve the sugar, which is crucial for creating the desired sweetness and consistency. Vanilla extract adds the iconic flavor that distinguishes vanilla syrup from other types of syrups.

Cornstarch, on the other hand, is not a component of traditional vanilla syrup. While cornstarch is commonly used as a thickening agent in various recipes, it is not necessary for the preparation of vanilla syrup, which relies on the simple combination of the other three ingredients to achieve its desired texture and flavor. Thus, the presence of cornstarch would not align with the classic recipe for vanilla syrup.
