Easter is the perfect time to try specialties of Portuguese cuisine. After  Lent, try traditional  roast kid, lamb stew, meatballs, sweet buns, dark chocolate and almond eggs.  In Castelo de Vide town in the Alentejo, you’ll experience a unique Easter celebration, one with Jewish origins. In the morning of Easter Eve, the region’s shepherds fill the town centre to have their flocks of sheep blessed. At night, during the Vigília Pascal (Paschal Vigil), people ask for forgiveness one-on-one, reminiscent of Yom Kippur. At the end of the mass, all those present bring cowbells that ring the Cortejo da Aleluia (Procession of Alleluia) through the town called Chocalhadas.
