The Spanish phrase "moldes para gelatina" means "gelatin molds." The word "moldes" translates in English as "molds," "para" means "for" and "gelatina" stands for "gelatin." Therefore, the Spanish phrase can also translate as "molds for gelatin."
Gelatin is a gel-like substance made from protein. It is most commonly known for its use as a gelling agent in foods, especially gelatin desserts such as Jell-O, and for its use in pharmaceutical products such as medicine capsules.
Gelatin molds are containers that cooks use when preparing gelatin desserts to give the food shape. These containers are available in a variety of shapes, such as hearts and rings.
