What is a cold biscuit?

A "cold biscuit" doesn't have a universally recognized meaning in the culinary world. It could refer to a few things, depending on context:

1. Biscuit Dough Made Ahead: This is the most common interpretation. It refers to biscuit dough that has been made and chilled in the refrigerator, often overnight. This chilling process helps develop the gluten in the flour, resulting in biscuits with a flakier texture.

2. Biscuits Served Cold: This is less common, but some people enjoy their biscuits chilled, especially if they are served with a warm topping or sauce.

3. Biscuits Made with a Cold Ingredient: Some biscuit recipes call for using cold butter or buttermilk to help create a flaky texture.

4. A Regional Term: In some regions, "cold biscuit" might be a local term for a specific type of biscuit.
