What is a popular topping that can be added to Melty 3 Cheese Tots?

Sour cream is a popular topping that complements Melty 3 Cheese Tots perfectly. The rich and creamy texture of sour cream enhances the savory flavors of the cheese and potatoes, adding a nice tanginess that balances the dish. Sour cream is commonly used as a condiment for various appetizers and sides, making it a familiar and well-loved choice among customers.

Options like chopped nuts, cucumber slices, and chocolate sauce do not typically align with the flavor profile or the intended taste experience of Melty 3 Cheese Tots. Chopped nuts may offer crunch but do not provide the creamy element that enhances the dish. Cucumber slices might add freshness, but they don't complement the cheesy, savory aspect. Chocolate sauce, while delicious in its own right, would introduce an inappropriate sweetness that clashes with the savory flavors of the cheese tots.
