On Christmas in Puerto Rico, the typical food is roast pork, also known as "lechon." It's a staple of the Christmas feast and is often accompanied by "arroz con gandules," rice with pigeon peas, and "pasteles," a type of Puerto Rican tamale made with plantains and stuffed with meat. Additionally, there may be various other side dishes such as salads, vegetables, and desserts like "tres leches cake" or "coquito," a sweet coconut rum-based beverage. It's a festive and delicious meal that is enjoyed by many Puerto Ricans during the holiday season.
