What is an essential characteristic of beijinho, a popular Brazilian sweet?

Beijinho, a beloved Brazilian sweet, is characterized primarily by its base of condensed milk. This key ingredient gives beijinho its creamy texture and sweetness. The preparation typically involves cooking the condensed milk with butter until it reaches a fudgy consistency, making it a rich and decadent treat.

While some variations might include a dusting of coconut or toppings, the essence of beijinho lies in its condensed milk foundation, which provides the signature flavor and consistency that makes it different from other sweets. Other options, such as containing nuts or being sour or savory, do not align with the traditional preparation and profile of beijinho.
