Arroz con gandules
Arroz con gandules is a combination of rice, pigeon peas, and pork, cooked in the same pot with sofrito. This is Puerto Rico's national dish along with roasted pork. This dish is mainly served during Christmas season or for special occasions. The sofrito is the most important part of seasoning the rice. In Puerto Rican cooking sofrito, which is used as a base in many recipes, typically consists of the following ingredients: Recao, cilantro, yellow onions, garlic, aji dulce peppers, cubanelle peppers, and tomatoes or tomato sauce. Sofrito is blended into a watery or paste consistency. The idea is for the rice to absorb the sofrito for maximum flavor. Tomatoes are typically roasted the day of preparation while the rest of the ingredients can be prepared together days in advance. The tomatoes are squeezed through a fine strainer discarding the seeds and skin. The day of cooking the first step is cooking the pigeon peas if they are being prepared from dried form or fresh, although the canned and frozen variety are widely available in Latino markets or supermarkets in cities where there is a significant Puerto Rican population. In a separate pot, annatto seeds are heated with an oil such as olive oil, or lard. The oil is strained and seeds are discarded. Annatto oil gives the rice a distinctive yellow/orange color.
