Gruyère is a type of cheese with a firm and creamy texture, known for its distinctively nutty and slightly sweet flavor. It originates from Switzerland and is often used in cooking, particularly in fondue and gratin dishes. The cheese has a pale yellow color and is characterized by its iconic small holes or "eyes." Gruyère is highly versatile and can be enjoyed on its own, melted over dishes, or incorporated into sandwiches and salads.
