Absolutely, you can add milk to melted chocolate. Doing so will make the chocolate smoother and more pourable, creating a mixture often used for making chocolate sauces, drizzles, or even hot chocolate. Adding a small amount of warm milk gradually to the melted chocolate while stirring gently helps in achieving a creamy consistency. Remember not to add too much milk as it can alter the chocolate’s texture or cause it to seize. For a delightful hot chocolate, I suggest warming the milk separately and then slowly incorporating it into the melted chocolate for a velvety, rich drink. My personal experience with this technique has always resulted in a delicious, smooth blend.
