Iberian Cebo Shoulder Ham 50% Iberian Breed origin Huelva 100g vacuum packed in blister. To preserve sliced Iberian ham, it's best to store it in a cool, dry place, at a stable temperature between 15 and 20 degrees Celsius, and protected from direct light. Refrigeration isn't necessary unless it's intended for long-term consumption. To protect the sliced portion, you can cover it with a clean cloth or plastic wrap, changing the wrap periodically to prevent condensation.
