For ➍55 cl water
80 g unsweetened cocoa powder
200 g sugar
170 g bittersweet chocolate (70% cocoa solids), chopped finely
pinch of salt
Freeze the bowl of an ice cream maker.
In a medium saucepan, whisk together the water, cocoa powder, and sugar. Set the pan over medium heat and bring to a boil, whisking continually. Remove from heat, and add the chopped chocolate.
Let rest for 30 s as the chocolate begins to melt, add the vanilla and salt, then stir until the chocolate is completely melted. Let cool on the counter, then refrigerate until chilled.
Whisk the mixture again just before using, and freeze in the ice cream maker.
