To prevent milk from boiling over, using a deep and wide pot makes a significant difference. Instead of high heat, slowly warming the milk on medium heat greatly reduces the risk of spillage. Regularly skimming the foam that forms on the surface of boiling milk is one of the most practical ways to prevent it from overflowing. Additionally, placing a wooden spoon across the rim of the pot or adding a few drops of water to the bottom of the pot can also prevent the milk from boiling over.
