1. Heat the milk gently on the stove and stir it slowly with a teaspoon.
2. When milk is heated, uneven stirring is easy to stick to the pot, and too fast stirring will affect the smooth taste.
3. When the milk is heated to about 50 degrees, add cocoa powder while stirring.
4. Continue to stir, so that the cocoa powder is evenly blended into the milk.
5. Heat the chocolate until it bubbles slightly, that is, about 90 degrees, then stop heating and fill the cup. If you like, you can sprinkle some cinnamon powder on the chocolate. If you are interested, you can also try rosemary, a small amount of pepper, Chili powder, ginger powder, nutmeg, walnut powder and other spices alone or in combination to cook hot chocolate with different flavors.
6. Add a little raw sugar appropriately, and the taste will be more charming.
