Rice and seafood are the key ingredients to making arroz marinero, a traditional specialty that originates from Spain. The main ingredients are usually combined with sautéed vegetables such as onions, peppers, tomatoes, and garlic, and the combination is typically simmered in water or stock (seafood or fish stock) with the addition of various spices and seasonings.
Like many other Spanish dishes, this one has also entered the traditional cuisines of the Spanish colonies with the introduction of rice and is nowadays associated with South American countries such as Peru, Ecuador, and Colombia. The variations on the dish abound throughout Spain and the Latin American countries, with each country having its own version of this rice specialty.
