1: Add the dark chocolate into a cup and top it with hot water. Allow it to sit for 2 minutes.
2: Once the chocolate has started to melt, mix it. Add instant coffee and salt, and mix again.
3: Foam the milk using a beater or a milk frother. Alternatively, in a heatproof tight jar, add the milk and sugar. Shake it vigorously for 30 seconds, taking care that it doesn’t spill.
4: Pour the foamed milk into the coffee chocolate mix. Dust it with some cocoa powder to garnish.
