Guava paste

Goiabada is a conserve made of red guavas and sugar, commonly found throughout the Portuguese-speaking countries of the world. It dates back to the colonial times of Brazil, where guavas were used as a substitute for the quinces used to make quince cheese. It required an abundance of sugar and slave labor for its production as it was made in large batches within cauldrons cooking over a slow fire. In rural areas of Brazil, it is still commonly made at home for family use or sale. Very similar to goiabada is the closely related Colombian bocadillo, also made from guava but with more sugar. It is known as guava paste or guava cheese throughout the English-speaking Americas, especially the Caribbean, and dulce de guayaba, barra de guayaba, pasta de guayaba, bocadillo or guayabate in Spanish-speaking Americas. It is commercially available, most often packaged in flat metal cans, or as long rectangular blocks in chipboard boxes.
