Bolo-Rainha, translating to "Queen Cake" in English, is a traditional cake that is closely related to the more commonly known Bolo Rei, or "King Cake." It is especially popular during the Christmas season and the festivities of the Epiphany (Dia de Reis) on January 6th.
Similar to Bolo Rei in its brioche-like texture, Bolo-Rainha is made with a rich, sweet dough. However, it differs primarily in its fillings and toppings. While Bolo Rei is characterized by its use of candied fruits, Bolo-Rainha typically does away with these candied fruits and instead focuses more on nuts like walnuts, almonds, and sometimes hazelnuts.
It also includes dried fruits such as raisins or sultanas. The top of Bolo-Rainha is adorned with a generous amount of nuts, giving it a distinct appearance compared to the colorful candied fruit topping of Bolo Rei. Like Bolo Rei, Bolo-Rainha is often baked with a hidden surprise inside, such as a small gift or a fava bean.
