2. After grinding the deeply roasted coffee beans, pour the coffee powder into a press, flatten the coffee powder with a pressure bar, and then buckle the press on the extraction port of an espresso machine to extract espresso (the ratio of coffee to fresh milk is 1: 1).
3. Put a proper amount of milk under the steam nozzle of the espresso machine and steam it into hot milk.
4. Pour the steamed milk into the cup.
5. Shake the cup up and down to make the milk foam rise.
6. Finally, slowly pour the espresso into the cup. Because the ratio of coffee to milk is 1: 1, when making orthodox French milk coffee, you have to hold the milk pot and coffee pot with both hands and pour them into the coffee cup at the same time, so you need considerable wrist strength. Because of the high latitude and cold climate in France, when drinking this kind of milk coffee, you usually use mugs and other cups, or use a large bowl without a handle, and keep the cup warm with both hands when drinking.
