Also known as Leiden, Boeren Leidse met sleutels, which translates to "Farmers' Leiden cheese with keys," the last word referring to the imprint of crossed keys on the rind, which represents Leiden's coat of arms. This cheese is semihard to hard with a firm, elastic texture. Leyden has a nutty and creamy flavor with spiciness coming from the embedded cumin seeds. It has an orangish-red rind or is covered in red plastic. See also cheese.
