A bottle of boiling milk might sound unconventional, but it is a convenient way to quickly heat milk while minimizing mess and direct contact with heat. This technique, used for generations in various cultures, typically involves placing a sealed or loosely covered glass or heat-safe plastic bottle in hot water or briefly in the microwave, rather than boiling the milk directly on the stove. The method ensures the milk heats gradually, reducing the risk of scorching, curdling, or spilling—a common problem when milk is heated directly in a pot.
